### What changes were proposed in this pull request?
This is to refactor Predicate code; it mainly removed `newPredicate` from `SparkPlan`.
Modifications are listed below;
- Move `Predicate` from `o.a.s.sqlcatalyst.expressions.codegen.GeneratePredicate.scala` to `o.a.s.sqlcatalyst.expressions.predicates.scala`
- To resolve the name conflict, rename `o.a.s.sqlcatalyst.expressions.codegen.Predicate` to `o.a.s.sqlcatalyst.expressions.BasePredicate`
- Extend `CodeGeneratorWithInterpretedFallback ` for `BasePredicate`
This comes from the cloud-fan suggestion: https://github.com/apache/spark/pull/26420#discussion_r348005497
### Why are the changes needed?
For better code/test coverage.
### Does this PR introduce any user-facing change?

### What changes were proposed in this pull request?
This PR fixes the issue of substituting aliases while collecting filters in `PhysicalOperation.collectProjectsAndFilters`. When the `AttributeReference` in alias map differs from the `AttributeReference` in filter condition only in qualifier, it does not substitute alias and throws exception saying `key videoid#47L not found` in the following scenario.
```
[1] Project [userid#0]
+- [2] Filter (isnotnull(videoid#47L) && NOT (videoid#47L = 30))
+- [3] Project [factorial(videoid#1) AS videoid#47L, userid#0]
+- [4] Filter (isnotnull(avebitrate#2) && (avebitrate#2 < 10))
+- [5] Relation[userid#0,videoid#1,avebitrate#2]
```
### Why are the changes needed?
We need to use `AttributeMap` where the key is `AttributeReference`'s `ExprId` instead of `Map[Attribute, Expression]` while collecting and substituting aliases in `PhysicalOperation.collectProjectsAndFilters`.
### Does this PR introduce any user-facing change?
No
### How was this patch tested?
New unit tests were added in `TestPhysicalOperation` which reproduces the bug

### What changes were proposed in this pull request?
Remove the special handling of the negative sign in the parser (interval literal and type constructor)
### Why are the changes needed?
The negative sign is an operator (UnaryMinus). We don't need to handle it specially, which is kind of doing constant folding at parser side.
### Does this PR introduce any user-facing change?
The error message becomes a little different. Now it reports type mismatch for the `-` operator.

modify Param._copyValues to check valid Param objects supplied as extra
### What changes were proposed in this pull request?
Estimator.fit() and Model.transform() accept a dictionary of extra parameters whose values are used to overwrite those supplied at initialization or by default. Additionally, the ParamGridBuilder.addGrid accepts a parameter and list of values. The keys are presumed to be valid Param objects. This change adds a check that only Param objects are supplied as keys.
### Why are the changes needed?
Param objects are created by and bound to an instance of Params (Estimator, Model, or Transformer). They may be obtained from their parent as attributes, or by name through getParam.
The documentation does not state that keys must be valid Param objects, nor describe how one may be obtained. The current behavior is to silently ignore keys which are not valid Param objects.
### Does this PR introduce any user-facing change?
If the user does not pass in a Param object as required for keys in `extra` for Estimator.fit() and Model.transform(), and `param` for ParamGridBuilder.addGrid, an error will be raised indicating it is an invalid object.
### How was this patch tested?
Added method test_copy_param_extras_check to test_param.py. Tested with Python 3.7

### What changes were proposed in this pull request?
Currently, we support to parse '1. second' to 1s or even '. second' to 0s.
```sql
-- !query 118
select interval '1. seconds'
-- !query 118 schema
struct<1 seconds:interval>
-- !query 118 output
1 seconds
-- !query 119
select interval '. seconds'
-- !query 119 schema
struct<0 seconds:interval>
-- !query 119 output
0 seconds
```
```sql
postgres=# select interval '1. second';
ERROR: invalid input syntax for type interval: "1. second"
LINE 1: select interval '1. second';
postgres=# select interval '. second';
ERROR: invalid input syntax for type interval: ". second"
LINE 1: select interval '. second';
```
We fix this by fixing the new interval parser's VALUE_FRACTIONAL_PART state

ONLY forbid the invalid interval value in the form of '. seconds'.

### What changes were proposed in this pull request?
This PR try to make sure the comparison results of `compared by 8 bytes at a time` and `compared by bytes wise` in RecordBinaryComparator is *consistent*, by reverse long bytes if it is little-endian and using Long.compareUnsigned.
### Why are the changes needed?
If the architecture supports unaligned or the offset is 8 bytes aligned, `RecordBinaryComparator` compare 8 bytes at a time by reading 8 bytes as a long. Related code is
```
if (Platform.unaligned() || (((leftOff + i) % 8 == 0) && ((rightOff + i) % 8 == 0))) {
while (i <= leftLen - 8) {
final long v1 = Platform.getLong(leftObj, leftOff + i);
final long v2 = Platform.getLong(rightObj, rightOff + i);
if (v1 != v2) {
return v1 > v2 ? 1 : -1;
}
i += 8;
}
}
```
Otherwise, it will compare bytes by bytes. Related code is
```
while (i < leftLen) {
final int v1 = Platform.getByte(leftObj, leftOff + i) & 0xff;
final int v2 = Platform.getByte(rightObj, rightOff + i) & 0xff;
if (v1 != v2) {
return v1 > v2 ? 1 : -1;
}
i += 1;
}
```
However, on little-endian machine, the result of *compared by a long value* and *compared bytes by bytes* maybe different.
For two same records, its offsets may vary in the first run and second run, which will lead to compare them using long comparison or byte-by-byte comparison, the result maybe different.

````
Most of cases occurred in reading a table which created by an old Spark version.
After recreated the table, the issue will be gone.
After deep dive, the root cause is this external table is a non-partitioned table but the `LOCATION` set to a partitioned path {{/tablename/dt=yyyymmdd}}. The partitionSpec is inferred.
### Why are the changes needed?
Above error message is very confused. We need more details about assert failure information.
This issue caused by `PartitioningAwareFileIndex#inferPartitioning()`. For non-HiveMetastore Spark, it's useful. But for Hive table, it shouldn't infer partition if Hive tell us it's a non partitioned table. (new added)

This is a followup of https://github.com/apache/spark/pull/26418. This PR removed `CalendarInterval`'s `toString` with an unfinished changes.
### Why are the changes needed?
1. Ideally we should make each PR isolated and separate targeting one issue without touching unrelated codes.
2. There are some other places where the string formats were exposed to users. For example:
```scala
scala> sql("select interval 1 days as a").selectExpr("to_csv(struct(a))").show()
```
```
+--------------------------+
|to_csv(named_struct(a, a))|
+--------------------------+
| "CalendarInterval...|
+--------------------------+
```
3. Such fixes:
```diff
private def writeMapData(
map: MapData, mapType: MapType, fieldWriter: ValueWriter): Unit = {
val keyArray = map.keyArray()
+ val keyString = mapType.keyType match {
+ case CalendarIntervalType =>
+ (i: Int) => IntervalUtils.toMultiUnitsString(keyArray.getInterval(i))
+ case _ => (i: Int) => keyArray.get(i, mapType.keyType).toString
+ }
```
can cause performance regression due to type dispatch for each map.

### What changes were proposed in this pull request?
Add AlterNamespaceSetLocationStatement, AlterNamespaceSetLocation, AlterNamespaceSetLocationExec to make ALTER DATABASE (SET LOCATION) look up catalog like v2 commands.
And also refine the code of AlterNamespaceSetProperties, AlterNamespaceSetPropertiesExec, DescribeNamespace, DescribeNamespaceExec to use SupportsNamespaces instead of CatalogPlugin for catalog parameter.
### Why are the changes needed?
It's important to make all the commands have the same catalog/namespace resolution behavior, to avoid confusing end-users.
### Does this PR introduce any user-facing change?
Yes, add "ALTER NAMESPACE ... SET LOCATION" whose function is same as "ALTER DATABASE ... SET LOCATION" and "ALTER SCHEMA ... SET LOCATION".
### How was this patch tested?

### What changes were proposed in this pull request?
We now have two different implementation for multi-units interval strings to CalendarInterval type values.
One is used to covert interval string literals to CalendarInterval. This approach will re-delegate the interval string to spark parser which handles the string as a `singleInterval` -> `multiUnitsInterval` -> eventually call `IntervalUtils.fromUnitStrings`
The other is used in `Cast`, which eventually calls `IntervalUtils.stringToInterval`. This approach is ~10 times faster than the other.
We should unify these two for better performance and simple logic. this pr uses the 2nd approach.
### Why are the changes needed?

### What changes were proposed in this pull request?
Add 3 interval output types which are named as `SQL_STANDARD`, `ISO_8601`, `MULTI_UNITS`. And we add a new conf `spark.sql.dialect.intervalOutputStyle` for this. The `MULTI_UNITS` style displays the interval values in the former behavior and it is the default. The newly added `SQL_STANDARD`, `ISO_8601` styles can be found in the following table.
Style | conf | Year-Month Interval | Day-Time Interval | Mixed Interval
-- | -- | -- | -- | --
Format With Time Unit Designators | MULTI_UNITS | 1 year 2 mons | 1 days 2 hours 3 minutes 4.123456 seconds | interval 1 days 2 hours 3 minutes 4.123456 seconds
SQL STANDARD | SQL_STANDARD | 1-2 | 3 4:05:06 | -1-2 3 -4:05:06

### What changes were proposed in this pull request?
I've noticed that there are two functions to sort arrays sort_array and array_sort.
sort_array is from 1.5.0 and it has the possibility of ordering both ascending and descending
array_sort is from 2.4.0 and it only has the possibility of ordering in ascending.
Basically I just added the possibility of ordering either ascending or descending using array_sort.
I think it would be good to have unified behaviours and not having to user sort_array when you want to order in descending order.
Imagine that you are new to spark, I'd like to be able to sort array using the newest spark functions.
### Why are the changes needed?
Basically to be able to sort the array in descending order using *array_sort* instead of using *sort_array* from 1.5.0
### Does this PR introduce any user-facing change?
Yes, now you are able to sort the array in descending order. Note that it has the same behaviour with nulls than sort_array

### What changes were proposed in this pull request?
Add a property `spark.fsUrlStreamHandlerFactory.enabled` to allow users turn off the default registration of `org.apache.hadoop.fs.FsUrlStreamHandlerFactory`
### Why are the changes needed?
This [SPARK-25694](https://issues.apache.org/jira/browse/SPARK-25694) is a long-standing issue. Originally, [[SPARK-12868][SQL] Allow adding jars from hdfs](https://github.com/apache/spark/pull/17342 ) added this for better Hive support. However, this have a side-effect when the users use Apache Spark without `-Phive`. This causes exceptions when the users tries to use another custom factories or 3rd party library (trying to set this). This configuration will unblock those non-hive users.
### Does this PR introduce any user-facing change?
Yes. This provides a new user-configurable property.
By default, the behavior is unchanged.
### How was this patch tested?
Manual testing.

This PR aims to make `lint-r` exits with non-zero in case of errors. Please note that `lint-r` works correctly when everything are installed correctly.
### Why are the changes needed?
There are two cases which hide errors from Jenkins/AppVeyor/GitHubAction.
1. `lint-r` exits with zero if there is no R installation.

```
2. `lint-r` exits with zero if we didn't do `R/install-dev.sh`.
```bash
$ dev/lint-r
Error: You should install SparkR in a local directory with `R/install-dev.sh`.
In addition: Warning message:

[[SPARK-29376] Upgrade Apache Arrow to version 0.15.1](https://github.com/apache/spark/pull/26133) upgrades to Arrow 0.15 at Scala/Java/Python. This PR aims to upgrade `SparkR` to use Arrow 0.15 API. Currently, it's broken.
### Why are the changes needed?
First of all, it turns out that our Jenkins jobs (including PR builder) ignores Arrow test. Arrow 0.15 has a breaking R API changes at [ARROW-5505](https://issues.apache.org/jira/browse/ARROW-5505) and we missed that. AppVeyor was the only one having SparkR Arrow tests but it's broken now.
**Jenkins**
```
Skipped ------------------------------------------------------------------------
1. createDataFrame/collect Arrow optimization (test_sparkSQL_arrow.R#25)
- arrow not installed
```
Second, Arrow throws OOM on AppVeyor environment (Windows JDK8) like the following because it still has Arrow 0.14.
```
Warnings -----------------------------------------------------------------------
1. createDataFrame/collect Arrow optimization (test_sparkSQL_arrow.R#39) - createDataFrame attempted Arrow optimization because 'spark.sql.execution.arrow.sparkr.enabled' is set to true; however, failed, attempting non-optimization. Reason: Error in handleErrors(returnStatus, conn): java.lang.OutOfMemoryError: Java heap space

at org.apache.spark.sql.execution.arrow.ArrowConverters$$anon$3.readNextBatch(ArrowConverters.scala:243)
```
It is due to the version mismatch.
```java
int messageLength = MessageSerializer.bytesToInt(buffer.array());
if (messageLength == IPC_CONTINUATION_TOKEN) {
buffer.clear();
// ARROW-6313, if the first 4 bytes are continuation message, read the next 4 for the length
if (in.readFully(buffer) == 4) {
messageLength = MessageSerializer.bytesToInt(buffer.array());
}
}
// Length of 0 indicates end of stream
if (messageLength != 0) {
// Read the message into the buffer.
ByteBuffer messageBuffer = ByteBuffer.allocate(messageLength);
```
After upgrading this to 0.15, we are hitting ARROW-5505. This PR upgrades Arrow version in AppVeyor and fix the issue.

No.

### What changes were proposed in this pull request?
Rename config "spark.sql.ansi.enabled" to "spark.sql.dialect.spark.ansi.enabled"
### Why are the changes needed?
The relation between "spark.sql.ansi.enabled" and "spark.sql.dialect" is confusing, since the "PostgreSQL" dialect should contain the features of "spark.sql.ansi.enabled".
To make things clearer, we can rename the "spark.sql.ansi.enabled" to "spark.sql.dialect.spark.ansi.enabled", thus the option "spark.sql.dialect.spark.ansi.enabled" is only for Spark dialect.
For the casting and arithmetic operations, runtime exceptions should be thrown if "spark.sql.dialect" is "spark" and "spark.sql.dialect.spark.ansi.enabled" is true or "spark.sql.dialect" is PostgresSQL.

### What changes were proposed in this pull request?
This PR aims to add `io.netty.tryReflectionSetAccessible=true` to the testing configuration for JDK11 because this is an officially documented requirement of Apache Arrow.

Add ```__repr__``` in Python ML Models
### Why are the changes needed?
In Python ML Models, some of them have ```__repr__```, others don't. In the doctest, when calling Model.setXXX, some of the Models print out the xxxModel... correctly, some of them can't because of lacking the ```__repr__``` method. For example:
```
>>> gm = GaussianMixture(k=3, tol=0.0001, seed=10)
>>> model = gm.fit(df)
>>> model.setPredictionCol("newPrediction")
GaussianMixture...
```
After the change, the above code will become the following:
```
>>> gm = GaussianMixture(k=3, tol=0.0001, seed=10)
>>> model = gm.fit(df)
>>> model.setPredictionCol("newPrediction")

### What changes were proposed in this pull request?
In order to avoid frequently changing the value of `spark.sql.adaptive.shuffle.maxNumPostShufflePartitions`, we usually set `spark.sql.adaptive.shuffle.maxNumPostShufflePartitions` much larger than `spark.sql.shuffle.partitions` after enabling adaptive execution, which causes some bucket map join lose efficacy and add more `ShuffleExchange`.
How to reproduce:
```scala
val bucketedTableName = "bucketed_table"
spark.range(10000).write.bucketBy(500, "id").sortBy("id").mode(org.apache.spark.sql.SaveMode.Overwrite).saveAsTable(bucketedTableName)
val bucketedTable = spark.table(bucketedTableName)
val df = spark.range(8)
spark.conf.set("spark.sql.autoBroadcastJoinThreshold", -1)
// Spark 2.4. spark.sql.adaptive.enabled=false
// We set spark.sql.shuffle.partitions <= 500 every time based on our data in this case.
spark.conf.set("spark.sql.shuffle.partitions", 500)
bucketedTable.join(df, "id").explain()
// Since 3.0. We enabled adaptive execution and set spark.sql.adaptive.shuffle.maxNumPostShufflePartitions to a larger values to fit more cases.
spark.conf.set("spark.sql.adaptive.enabled", true)
spark.conf.set("spark.sql.adaptive.shuffle.maxNumPostShufflePartitions", 1000)
bucketedTable.join(df, "id").explain()
```
```

This PR makes read bucketed tables always obeys `spark.sql.shuffle.partitions` even enabling adaptive execution and set `spark.sql.adaptive.shuffle.maxNumPostShufflePartitions` to avoid add more `ShuffleExchange`.
### Why are the changes needed?
Do not degrade performance after enabling adaptive execution.
### Does this PR introduce any user-facing change?
No.
### How was this patch tested?
Unit test.
