The PR adds new function `from_csv()` similar to `from_json()` to parse columns with CSV strings. I added the following methods:
```Scala
def from_csv(e: Column, schema: StructType, options: Map[String, String]): Column
```
and this signature to call it from Python, R and Java:
```Scala
def from_csv(e: Column, schema: String, options: java.util.Map[String, String]): Column
```
## How was this patch tested?
Added new test suites `CsvExpressionsSuite`, `CsvFunctionsSuite` and sql tests.

According to the SQL standard, when a query contains `HAVING`, it indicates an aggregate operator. For more details please refer to https://blog.jooq.org/2014/12/04/do-you-really-understand-sqls-group-by-and-having-clauses/
However, in Spark SQL parser, we treat HAVING as a normal filter when there is no GROUP BY, which breaks SQL semantic and lead to wrong result. This PR fixes the parser.

The HandleNullInputsForUDF rule can generate new If node infinitely, thus causing problems like match of SQL cache missed.
This was fixed in SPARK-24891 and was then broken by SPARK-25044.
The unit test in `AnalysisSuite` added in SPARK-24891 should have failed but didn't because it wasn't properly updated after the `ScalaUDF` constructor signature change. So this PR also updates the test accordingly based on the new `ScalaUDF` constructor.
## How was this patch tested?

This PR can correctly cause assertion failure when incorrect nullable of DataType in the result is generated by a target function to be tested.
Let us think the following example. In the future, a developer would write incorrect code that returns unexpected result. We have to correctly cause fail in this test since `valueContainsNull=false` while `expr` includes `null`. However, without this PR, this test passes. This PR can correctly cause fail.
```
test("test TARGETFUNCTON") {
val expr = TARGETMAPFUNCTON()
// expr = UnsafeMap(3 -> 6, 7 -> null)
// expr.dataType = (IntegerType, IntegerType, false)
expected = Map(3 -> 6, 7 -> null)
checkEvaluation(expr, expected)
```
In [`checkEvaluationWithUnsafeProjection`](https://github.com/apache/spark/blob/master/sql/catalyst/src/test/scala/org/apache/spark/sql/catalyst/expressions/ExpressionEvalHelper.scala#L208-L235), the results are compared using `UnsafeRow`. When the given `expected` is [converted](https://github.com/apache/spark/blob/master/sql/catalyst/src/test/scala/org/apache/spark/sql/catalyst/expressions/ExpressionEvalHelper.scala#L226-L227)) to `UnsafeRow` using the `DataType` of `expr`.
```
val expectedRow = UnsafeProjection.create(Array(expression.dataType, expression.dataType)).apply(lit)
```
In summary, `expr` is `[0,1800000038,5000000038,18,2,0,700000003,2,0,6,18,2,0,700000003,2,0,6]` with and w/o this PR. `expected` is converted to
* w/o this PR, `[0,1800000038,5000000038,18,2,0,700000003,2,0,6,18,2,0,700000003,2,0,6]`
* with this PR, `[0,1800000038,5000000038,18,2,0,700000003,2,2,6,18,2,0,700000003,2,2,6]`
As a result, w/o this PR, the test unexpectedly passes.
This is because, w/o this PR, based on given `dataType`, generated code of projection for `expected` avoids to set nullbit.
```
// tmpInput_2 is expected
/* 155 */ for (int index_1 = 0; index_1 < numElements_1; index_1++) {
/* 156 */ mutableStateArray_1[1].write(index_1, tmpInput_2.getInt(index_1));
/* 157 */ }
```
With this PR, generated code of projection for `expected` always checks whether nullbit should be set by `isNullAt`
```
// tmpInput_2 is expected
/* 161 */ for (int index_1 = 0; index_1 < numElements_1; index_1++) {
/* 162 */
/* 163 */ if (tmpInput_2.isNullAt(index_1)) {
/* 164 */ mutableStateArray_1[1].setNull4Bytes(index_1);
/* 165 */ } else {
/* 166 */ mutableStateArray_1[1].write(index_1, tmpInput_2.getInt(index_1));
/* 167 */ }
/* 168 */
/* 169 */ }
```

While working on another PR, I noticed that there is quite some legacy Java in there that can be beautified. For example the use of features from Java8, such as:
- Collection libraries
- Try-with-resource blocks
No logic has been changed. I think it is important to have a solid codebase with examples that will inspire next PR's to follow up on the best practices.
What are your thoughts on this?
This makes code easier to read, and using try-with-resource makes is less likely to forget to close something.
## What changes were proposed in this pull request?
No changes in the logic of Spark, but more in the aesthetics of the code.

Hi all,
Jackson is incompatible with upstream versions, therefore bump the Jackson version to a more recent one. I bumped into some issues with Azure CosmosDB that is using a more recent version of Jackson. This can be fixed by adding exclusions and then it works without any issues. So no breaking changes in the API's.
I would also consider bumping the version of Jackson in Spark. I would suggest to keep up to date with the dependencies, since in the future this issue will pop up more frequently.

The PR changes the test introduced for SPARK-22226, so that we don't run analysis and optimization on the plan. The scope of the test is code generation and running the above mentioned operation is expensive and useless for the test.

## What changes were proposed in this pull request?
In #20850 when writing non-null decimals, instead of zero-ing all the 16 allocated bytes, we zero-out only the padding bytes. Since we always allocate 16 bytes, if the number of bytes needed for a decimal is lower than 9, then this means that the bytes between 8 and 16 are not zero-ed.
I see 2 solutions here:
- we can zero-out all the bytes in advance as it was done before #20850 (safer solution IMHO);
- we can allocate only the needed bytes (may be a bit more efficient in terms of memory used, but I have not investigated the feasibility of this option).
Hence I propose here the first solution in order to fix the correctness issue. We can eventually switch to the second if we think is more efficient later.

This PR adds a rule to force `.toLowerCase(Locale.ROOT)` or `toUpperCase(Locale.ROOT)`.
It produces an error as below:
```
[error] Are you sure that you want to use toUpperCase or toLowerCase without the root locale? In most cases, you
[error] should use toUpperCase(Locale.ROOT) or toLowerCase(Locale.ROOT) instead.
[error] If you must use toUpperCase or toLowerCase without the root locale, wrap the code block with
[error] // scalastyle:off caselocale
[error] .toUpperCase
[error] .toLowerCase
[error] // scalastyle:on caselocale
```
This PR excludes the cases above for SQL code path for external calls like table name, column name and etc.
For test suites, or when it's clear there's no locale problem like Turkish locale problem, it uses `Locale.ROOT`.
One minor problem is, `UTF8String` has both methods, `toLowerCase` and `toUpperCase`, and the new rule detects them as well. They are ignored.

In ElementAt, when first argument is MapType, we should coerce the key type and the second argument based on findTightestCommonType. This is not happening currently. We may produce wrong output as we will incorrectly downcast the right hand side double expression to int.
```SQL
spark-sql> select element_at(map(1,"one", 2, "two"), 2.2);
two
```
Also, when the first argument is ArrayType, the second argument should be an integer type or a smaller integral type that can be safely casted to an integer type. Currently we may do an unsafe cast. In the following case, we should fail with an error as 2.2 is not a integer index. But instead we down cast it to int currently and return a result instead.
```SQL
spark-sql> select element_at(array(1,2), 1.24D);
1
```
This PR also supports implicit cast between two MapTypes. I have followed similar logic that exists today to do implicit casts between two array types.

The problem was cause by the PushProjectThroughUnion rule, which, when creating new Project for each child of Union, uses the same exprId for expressions of the same position. This is wrong because, for each child of Union, the expressions are all independent, and it can lead to a wrong result if other rules like FoldablePropagation kicks in, taking two different expressions as the same.
This fix is to create new expressions in the new Project for each child of Union.

The PR restores the previous behavior and makes their resolution case insensitive anyhow. The PR takes over #21217, therefore it closes#21217 and credit for this patch should be given to jamesthomp.

The PR takes over #14036 and it introduces a new expression `IntegralDivide` in order to avoid the several unneded cast added previously.
In order to prove the performance gain, the following benchmark has been run:
```
test("Benchmark IntegralDivide") {
val r = new scala.util.Random(91)
val nData = 1000000
val testDataInt = (1 to nData).map(_ => (r.nextInt(), r.nextInt()))
val testDataLong = (1 to nData).map(_ => (r.nextLong(), r.nextLong()))
val testDataShort = (1 to nData).map(_ => (r.nextInt().toShort, r.nextInt().toShort))
// old code
val oldExprsInt = testDataInt.map(x =>
Cast(Divide(Cast(Literal(x._1), DoubleType), Cast(Literal(x._2), DoubleType)), LongType))
val oldExprsLong = testDataLong.map(x =>
Cast(Divide(Cast(Literal(x._1), DoubleType), Cast(Literal(x._2), DoubleType)), LongType))
val oldExprsShort = testDataShort.map(x =>
Cast(Divide(Cast(Literal(x._1), DoubleType), Cast(Literal(x._2), DoubleType)), LongType))
// new code
val newExprsInt = testDataInt.map(x => IntegralDivide(x._1, x._2))
val newExprsLong = testDataLong.map(x => IntegralDivide(x._1, x._2))
val newExprsShort = testDataShort.map(x => IntegralDivide(x._1, x._2))
Seq(("Long", "old", oldExprsLong),
("Long", "new", newExprsLong),
("Int", "old", oldExprsInt),
("Int", "new", newExprsShort),
("Short", "old", oldExprsShort),
("Short", "new", oldExprsShort)).foreach { case (dt, t, ds) =>
val start = System.nanoTime()
ds.foreach(e => e.eval(EmptyRow))
val endNoCodegen = System.nanoTime()
println(s"Running $nData op with $t code on $dt (no-codegen): ${(endNoCodegen - start) / 1000000} ms")
}
}
```
The results on my laptop are:
```
Running 1000000 op with old code on Long (no-codegen): 600 ms
Running 1000000 op with new code on Long (no-codegen): 112 ms
Running 1000000 op with old code on Int (no-codegen): 560 ms
Running 1000000 op with new code on Int (no-codegen): 135 ms
Running 1000000 op with old code on Short (no-codegen): 317 ms
Running 1000000 op with new code on Short (no-codegen): 153 ms
```
Showing a 2-5X improvement. The benchmark doesn't include code generation as it is pretty hard to test the performance there as for such simple operations the most of the time is spent in the code generation/compilation process.

In RuleExecutor, after applying a rule, if the plan has changed, the before and after plan will be logged using level "trace". At times, however, such information can be very helpful for debugging. Hence, making the log level configurable in SQLConf would allow users to turn on the plan change log independently and save the trouble of tweaking log4j settings. Meanwhile, filtering plan change log for specific rules can also be very useful.
So this PR adds two SQL configurations:
1. spark.sql.optimizer.planChangeLog.level - set a specific log level for logging plan changes after a rule is applied.
2. spark.sql.optimizer.planChangeLog.rules - enable plan change logging only for a set of specified rules, separated by commas.

When running TPC-DS benchmarks on 2.4 release, npoggi and winglungngai saw more than 10% performance regression on the following queries: q67, q24a and q24b. After we applying the PR https://github.com/apache/spark/pull/22338, the performance regression still exists. If we revert the changes in https://github.com/apache/spark/pull/19222, npoggi and winglungngai found the performance regression was resolved. Thus, this PR is to revert the related changes for unblocking the 2.4 release.
In the future release, we still can continue the investigation and find out the root cause of the regression.

_N.B. This is a restart of PR #16578 which includes a subset of that code. Relevant review comments from that PR should be considered incorporated by reference. Please avoid duplication in review by reviewing that PR first. The summary below is an edited copy of the summary of the previous PR._
## What changes were proposed in this pull request?
One of the hallmarks of a column-oriented data storage format is the ability to read data from a subset of columns, efficiently skipping reads from other columns. Spark has long had support for pruning unneeded top-level schema fields from the scan of a parquet file. For example, consider a table, `contacts`, backed by parquet with the following Spark SQL schema:
```
root
|-- name: struct
| |-- first: string
| |-- last: string
|-- address: string
```
Parquet stores this table's data in three physical columns: `name.first`, `name.last` and `address`. To answer the query
```SQL
select address from contacts
```
Spark will read only from the `address` column of parquet data. However, to answer the query
```SQL
select name.first from contacts
```
Spark will read `name.first` and `name.last` from parquet.
This PR modifies Spark SQL to support a finer-grain of schema pruning. With this patch, Spark reads only the `name.first` column to answer the previous query.
### Implementation
There are two main components of this patch. First, there is a `ParquetSchemaPruning` optimizer rule for gathering the required schema fields of a `PhysicalOperation` over a parquet file, constructing a new schema based on those required fields and rewriting the plan in terms of that pruned schema. The pruned schema fields are pushed down to the parquet requested read schema. `ParquetSchemaPruning` uses a new `ProjectionOverSchema` extractor for rewriting a catalyst expression in terms of a pruned schema.
Second, the `ParquetRowConverter` has been patched to ensure the ordinals of the parquet columns read are correct for the pruned schema. `ParquetReadSupport` has been patched to address a compatibility mismatch between Spark's built in vectorized reader and the parquet-mr library's reader.
### Limitation
Among the complex Spark SQL data types, this patch supports parquet column pruning of nested sequences of struct fields only.
## How was this patch tested?
Care has been taken to ensure correctness and prevent regressions. A more advanced version of this patch incorporating optimizations for rewriting queries involving aggregations and joins has been running on a production Spark cluster at VideoAmp for several years. In that time, one bug was found and fixed early on, and we added a regression test for that bug.
We forward-ported this patch to Spark master in June 2016 and have been running this patch against Spark 2.x branches on ad-hoc clusters since then.

Closes#22070 from seratch/fix-typo.
Authored-by: Kazuhiro Sera <seratch@gmail.com>
Signed-off-by: Sean Owen <srowen@gmail.com>
## What changes were proposed in this pull request?
This is a follow-up to #21305 that adds a test suite for AppendData analysis.
This also fixes the following problems uncovered by these tests:
* Incorrect order of data types passed to `canWrite` is fixed
* The field check calls `canWrite` first to ensure all errors are found
* `AppendData#resolved` must check resolution of the query's attributes
* Column names are quoted to show empty names
## How was this patch tested?
This PR adds a test suite for AppendData analysis.

## What changes were proposed in this pull request?
This PR addresses two issues in `BufferHolderSparkSubmitSuite`.
1. While `BufferHolderSparkSubmitSuite` tried to allocate a large object several times, it actually allocated an object once and reused the object.
2. `BufferHolderSparkSubmitSuite` may fail due to timeout
To assign a small object before allocating a large object each time solved issue 1 by avoiding reuse.
To increasing heap size from 4g to 7g solved issue 2. It can also avoid OOM after fixing issue 1.
## How was this patch tested?
Updated existing `BufferHolderSparkSubmitSuite`

## What changes were proposed in this pull request?
We have completed a significant subset of the object related Expressions to provide an interpreted fallback. This PR is going to modify the tests to also test the interpreted code paths.
One concern right now is that by testing the interpreted code paths too, we will double current test time or more. Otherwise, we can only choose to test the interpreted code paths for just few test suites such as encoder related.

This PR fixes an exception during the compilation of generated code of `mapEntry`. This error occurs since the current code uses `key` type to store a `value` when `key` and `value` types are primitive type.

* A new analyzer rule, ResolveOutputColumns, validates data before it is appended. This rule will add safe casts, rename columns, and checks nullability
## How was this patch tested?
Existing tests for v2 appends. Will add AppendData tests to validate logical plan analysis.
Closes#21305 from rdblue/SPARK-24251-add-append-data.

## What changes were proposed in this pull request?
The design details is attached to the JIRA issue [here](https://drive.google.com/file/d/1zKm3aNZ3DpsqIuoMvRsf0kkDkXsAasxH/view)
High level overview of the changes are:
- Enhance the qualifier to be more than one string
- Add support to store the qualifier. Enhance the lookupRelation to keep the qualifier appropriately.
- Enhance the table matching column resolution algorithm to account for qualifier being more than a string.
- Enhance the table matching algorithm in UnresolvedStar.expand
- Ensure that we continue to support select t1.i1 from db1.t1
## How was this patch tested?
- New tests are added.
- Several test scenarios were added in a separate [test pr 17067](https://github.com/apache/spark/pull/17067). The tests that were not supported earlier are marked with TODO markers and those are now supported with the code changes here.
- Existing unit tests ( hive, catalyst and sql) were run successfully.

## What changes were proposed in this pull request?
Using struct types in subqueries with the `IN` clause can generate invalid plans in `RewritePredicateSubquery`. Indeed, we are not handling clearly the cases when the outer value is a struct or the output of the inner subquery is a struct.
The PR aims to make Spark's behavior the same as the one of the other RDBMS - namely Oracle and Postgres behavior were checked. So we consider valid only queries having the same number of fields in the outer value and in the subquery. This means that:
- `(a, b) IN (select c, d from ...)` is a valid query;
- `(a, b) IN (select (c, d) from ...)` throws an AnalysisException, as in the subquery we have only one field of type struct while in the outer value we have 2 fields;
- `a IN (select (c, d) from ...)` - where `a` is a struct - is a valid query.

Having the default value of isAll in the logical plan nodes INTERSECT/EXCEPT could introduce bugs when the callers are not aware of it. This PR removes the default value and makes caller explicitly specify them.

This pr adds `aggregate` function which applies a binary operator to an initial state and all elements in the array, and reduces this to a single state. The final state is converted into the final result by applying a finish function.

6
> SELECT aggregate(array(1, 2, 3), (acc, x) -> acc + x, acc -> acc * 10);

## What changes were proposed in this pull request?
Many Spark SQL users in my company have asked for a way to control the number of output files in Spark SQL. The users prefer not to use function repartition(n) or coalesce(n, shuffle) that require them to write and deploy Scala/Java/Python code. We propose adding the following Hive-style Coalesce and Repartition Hint to Spark SQL:
```
... SELECT /*+ COALESCE(numPartitions) */ ...
... SELECT /*+ REPARTITION(numPartitions) */ ...
```
Multiple such hints are allowed. Multiple nodes are inserted into the logical plan, and the optimizer will pick the leftmost hint.
```
INSERT INTO s SELECT /*+ REPARTITION(100), COALESCE(500), COALESCE(10) */ * FROM t
== Logical Plan ==
'InsertIntoTable 'UnresolvedRelation `s`, false, false
+- 'UnresolvedHint REPARTITION, [100]
+- 'UnresolvedHint COALESCE, [500]
+- 'UnresolvedHint COALESCE, [10]
+- 'Project [*]
+- 'UnresolvedRelation `t`
== Optimized Logical Plan ==
InsertIntoHadoopFsRelationCommand ...
+- Repartition 100, true
+- HiveTableRelation ...
```

## What changes were proposed in this pull request?
Currently the set operations INTERSECT, UNION and EXCEPT are assigned the same precedence. This PR fixes the problem by giving INTERSECT higher precedence than UNION and EXCEPT. UNION and EXCEPT operators are evaluated in the order in which they appear in the query from left to right.
This results in change in behavior because of the change in order of evaluations of set operators in a query. The old behavior is still preserved under a newly added config parameter.
Query `:`
```
SELECT * FROM t1
UNION
SELECT * FROM t2
EXCEPT
SELECT * FROM t3
INTERSECT
SELECT * FROM t4
```
Parsed plan before the change `:`

- Update DateTimeUtilsSuite so that when testing roundtripping in daysToMillis and millisToDays multiple skipdates can be specified.
- Updated test so that both new years eve 2014 and new years day 2015 are skipped for kiribati time zones. This is necessary as java versions pre 181-b13 considered new years day 2015 to be skipped while susequent versions corrected this to new years eve.

## What changes were proposed in this pull request?
Implements EXCEPT ALL clause through query rewrites using existing operators in Spark. In this PR, an internal UDTF (replicate_rows) is added to aid in preserving duplicate rows. Please refer to [Link](https://drive.google.com/open?id=1nyW0T0b_ajUduQoPgZLAsyHK8s3_dko3ulQuxaLpUXE) for the design.
**Note** This proposed UDTF is kept as a internal function that is purely used to aid with this particular rewrite to give us flexibility to change to a more generalized UDTF in future.
Input Query
``` SQL
SELECT c1 FROM ut1 EXCEPT ALL SELECT c1 FROM ut2
```
Rewritten Query
```SQL
SELECT c1
FROM (
SELECT replicate_rows(sum_val, c1)
FROM (
SELECT c1, sum_val
FROM (
SELECT c1, sum(vcol) AS sum_val
FROM (
SELECT 1L as vcol, c1 FROM ut1
UNION ALL
SELECT -1L as vcol, c1 FROM ut2
) AS union_all
GROUP BY union_all.c1
)
WHERE sum_val > 0

## What changes were proposed in this pull request?
AnalysisBarrier was introduced in SPARK-20392 to improve analysis speed (don't re-analyze nodes that have already been analyzed).
Before AnalysisBarrier, we already had some infrastructure in place, with analysis specific functions (resolveOperators and resolveExpressions). These functions do not recursively traverse down subplans that are already analyzed (with a mutable boolean flag _analyzed). The issue with the old system was that developers started using transformDown, which does a top-down traversal of the plan tree, because there was not top-down resolution function, and as a result analyzer performance became pretty bad.
In order to fix the issue in SPARK-20392, AnalysisBarrier was introduced as a special node and for this special node, transform/transformUp/transformDown don't traverse down. However, the introduction of this special node caused a lot more troubles than it solves. This implicit node breaks assumptions and code in a few places, and it's hard to know when analysis barrier would exist, and when it wouldn't. Just a simple search of AnalysisBarrier in PR discussions demonstrates it is a source of bugs and additional complexity.
Instead, this pull request removes AnalysisBarrier and reverts back to the old approach. We added infrastructure in tests that fail explicitly if transform methods are used in the analyzer.
## How was this patch tested?
Added a test suite AnalysisHelperSuite for testing the resolve* methods and transform* methods.

## What changes were proposed in this pull request?
This is an extension to the original PR, in which rule exclusion did not work for classes derived from Optimizer, e.g., SparkOptimizer.
To solve this issue, Optimizer and its derived classes will define/override `defaultBatches` and `nonExcludableRules` in order to define its default rule set as well as rules that cannot be excluded by the SQL config. In the meantime, Optimizer's `batches` method is dedicated to the rule exclusion logic and is defined "final".
## How was this patch tested?
Added UT.

## What changes were proposed in this pull request?
In the PR, I propose to extend the `StructType`/`StructField` classes by new method `toDDL` which converts a value of the `StructType`/`StructField` type to a string formatted in DDL style. The resulted string can be used in a table creation.
The `toDDL` method of `StructField` is reused in `SHOW CREATE TABLE`. In this way the PR fixes the bug of unquoted names of nested fields.
## How was this patch tested?
I add a test for checking the new method and 2 round trip tests: `fromDDL` -> `toDDL` and `toDDL` -> `fromDDL`

## What changes were proposed in this pull request?
The HandleNullInputsForUDF would always add a new `If` node every time it is applied. That would cause a difference between the same plan being analyzed once and being analyzed twice (or more), thus raising issues like plan not matched in the cache manager. The solution is to mark the arguments as null-checked, which is to add a "KnownNotNull" node above those arguments, when adding the UDF under an `If` node, because clearly the UDF will not be called when any of those arguments is null.
## How was this patch tested?
Add new tests under sql/UDFSuite and AnalysisSuite.

Closes#21851 from maryannxue/spark-24891.
