## What changes were proposed in this pull request?
In type coercion for complex types, if the found type is force-nullable to cast, we should loosen the nullability to be able to cast. Also for map key type, we can't use the type.
## How was this patch tested?
Added some test.

## What changes were proposed in this pull request?
"distribute by" on multiple columns (wrap in brackets) may lead to codegen issue.
Simple way to reproduce:
```scala
val df = spark.range(1000)
val columns = (0 until 400).map{ i => s"id as id$i" }
val distributeExprs = (0 until 100).map(c => s"id$c").mkString(",")
df.selectExpr(columns : _*).createTempView("test")
spark.sql(s"select * from test distribute by ($distributeExprs)").count()
```

## What changes were proposed in this pull request?
A logical `Limit` is performed physically by two operations `LocalLimit` and `GlobalLimit`.
Most of time, we gather all data into a single partition in order to run `GlobalLimit`. If we use a very big limit number, shuffling data causes performance issue also reduces parallelism.
We can avoid shuffling into single partition if we don't care data ordering. This patch implements this idea by doing a map stage during global limit. It collects the info of row numbers at each partition. For each partition, we locally retrieves limited data without any shuffling to finish this global limit.
For example, we have three partitions with rows (100, 100, 50) respectively. In global limit of 100 rows, we may take (34, 33, 33) rows for each partition locally. After global limit we still have three partitions.
If the data partition has certain ordering, we can't distribute required rows evenly to each partitions because it could change data ordering. But we still can avoid shuffling.
## How was this patch tested?
Jenkins tests.

## What changes were proposed in this pull request?
Support for text socket stream in spark structured streaming "continuous" mode. This is roughly based on the idea of ContinuousMemoryStream where the executor queries the data from driver over an RPC endpoint.
This makes it possible to create Structured streaming continuous pipeline to ingest data via "nc" and run examples.
## How was this patch tested?
Unit test and ran spark examples in structured streaming continuous mode.

* 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.

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.

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.

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?

In the PR, I propose to replace Scala parallel collections by new methods `parmap()`. The methods use futures to transform a sequential collection by applying a lambda function to each element in parallel. The result of `parmap` is another regular (sequential) collection.
The proposed `parmap` method aims to solve the problem of impossibility to interrupt parallel Scala collection. This possibility is needed for reliable task preemption.

## 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.

Like Uuid in SPARK-24896, Rand and Randn expressions now produce the same results for each execution in streaming query. It doesn't make too much sense for streaming queries. We should make them produce different results as Uuid.
In this change, similar to Uuid, we assign new random seeds to Rand/Randn when returning optimized plan from `IncrementalExecution`.
Note: Different to Uuid, Rand/Randn can be created with initial seed. Because we replace this initial seed at `IncrementalExecution`, it doesn't use the initial seed anymore. For now it seems to me not a big issue for streaming query. But need to confirm with others. cc zsxwing cloud-fan

It doesn't work with structured streaming: it requires query is already started, and the information can be retrieved from StreamingQuery, not Dataset. I guess that's why "explain" had to be placed to StreamingQuery whereas it already exists on Dataset.
This patch adds a new implicit class "DebugStreamQuery" which matches StreamingQuery to provide similar debug features on StreamingQuery class.
## How was this patch tested?
Added relevant unit tests.

Closes#21222 from HeartSaVioR/SPARK-24161.
## What changes were proposed in this pull request?
During upgrading Apache ORC to 1.5.2 ([SPARK-24576](https://issues.apache.org/jira/browse/SPARK-24576)), `sql/core` module overrides the exclusion rules of parent pom file and it causes published `spark-sql_2.1X` artifacts have incomplete exclusion rules ([SPARK-25019](https://issues.apache.org/jira/browse/SPARK-25019)). This PR fixes it by moving the newly added exclusion rule to the parent pom. This also fixes the sbt build hack introduced at that time.
## How was this patch tested?

## What changes were proposed in this pull request?
The PR adds the SQL function `array_intersect`. The behavior of the function is based on Presto's one.
This function returns returns an array of the elements in the intersection of array1 and array2.
Note: The order of elements in the result is not defined.

Closes#21102 from kiszk/SPARK-23913.
## What changes were proposed in this pull request?
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.
## How was this patch tested?
This is a refactoring change. Existing tests test the functionality already.

Author: Wenchen Fan <wenchen@databricks.com>
Closes#21948 from cloud-fan/row-write.
## What changes were proposed in this pull request?
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.
```sql
> SELECT aggregate(array(1, 2, 3), (acc, x) -> acc + x);
6
> SELECT aggregate(array(1, 2, 3), (acc, x) -> acc + x, acc -> acc * 10);
60
```
