## What changes were proposed in this pull request?
This patch exposes the estimation of size of cache (loadedMaps) in HDFSBackedStateStoreProvider as a custom metric of StateStore.
The rationalize of the patch is that state backed by HDFSBackedStateStoreProvider will consume more memory than the number what we can get from query status due to caching multiple versions of states. The memory footprint to be much larger than query status reports in situations where the state store is getting a lot of updates: while shallow-copying map incurs additional small memory usages due to the size of map entities and references, but row objects will still be shared across the versions. If there're lots of updates between batches, less row objects will be shared and more row objects will exist in memory consuming much memory then what we expect.
While HDFSBackedStateStore refers loadedMaps in HDFSBackedStateStoreProvider directly, there would be only one `StateStoreWriter` which refers a StateStoreProvider, so the value is not exposed as well as being aggregated multiple times. Current state metrics are safe to aggregate for the same reason.

In https://issues.apache.org/jira/browse/SPARK-24924, the data source provider com.databricks.spark.avro is mapped to the new package org.apache.spark.sql.avro .
As per the discussion in the [Jira](https://issues.apache.org/jira/browse/SPARK-24924) and PR #22119, we should make the mapping configurable.
This PR also improve the error message when data source of Avro/Kafka is not found.

## What changes were proposed in this pull request?
This patch proposes a new flag option for stateful aggregation: remove redundant key data from value.
Enabling new option runs similar with current, and uses less memory for state according to key/value fields of state operator.
Please refer below link to see detailed perf. test result:
https://issues.apache.org/jira/browse/SPARK-24763?focusedCommentId=16536539&page=com.atlassian.jira.plugin.system.issuetabpanels%3Acomment-tabpanel#comment-16536539
Since the state between enabling the option and disabling the option is not compatible, the option is set to 'disable' by default (to ensure backward compatibility), and OffsetSeqMetadata would prevent modifying the option after executing query.
## How was this patch tested?
Modify unit tests to cover both disabling option and enabling option.
Also did manual tests to see whether propose patch improves state memory usage.

Spark SQL returns NULL for a column whose Hive metastore schema and Parquet schema are in different letter cases, regardless of spark.sql.caseSensitive set to true or false. This PR aims to add case-insensitive field resolution for ParquetFileFormat.
* Do case-insensitive resolution only if Spark is in case-insensitive mode.
* Field resolution should fail if there is ambiguity, i.e. more than one field is matched.

In the PR, I propose to skip invoking of the CSV/JSON parser per each line in the case if the required schema is empty. Added benchmarks for `count()` shows performance improvement up to **3.5 times**.
Before:
```
Count a dataset with 10 columns: Best/Avg Time(ms) Rate(M/s) Per Row(ns)
--------------------------------------------------------------------------------------
JSON count() 7676 / 7715 1.3 767.6
CSV count() 3309 / 3363 3.0 330.9
```
After:
```
Count a dataset with 10 columns: Best/Avg Time(ms) Rate(M/s) Per Row(ns)
--------------------------------------------------------------------------------------
JSON count() 2104 / 2156 4.8 210.4

## What changes were proposed in this pull request?
The PR removes a restriction for element types of array type which exists in `from_json` for the root type. Currently, the function can handle only arrays of structs. Even array of primitive types is disallowed. The PR allows arrays of any types currently supported by JSON datasource. Here is an example of an array of a primitive type:
```
scala> import org.apache.spark.sql.functions._
scala> val df = Seq("[1, 2, 3]").toDF("a")
scala> val schema = new ArrayType(IntegerType, false)
scala> val arr = df.select(from_json($"a", schema))
scala> arr.printSchema
root
|-- jsontostructs(a): array (nullable = true)
| |-- element: integer (containsNull = true)
```
and result of converting of the json string to the `ArrayType`:
```
scala> arr.show
+----------------+
|jsontostructs(a)|
+----------------+
| [1, 2, 3]|
+----------------+
```
## How was this patch tested?
I added a few positive and negative tests:
- array of primitive types
- array of arrays
- array of structs
- array of maps

## 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.

## 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.

## What changes were proposed in this pull request?
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.

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

This PR refactors `ArrayUnion` based on [this suggestion](https://github.com/apache/spark/pull/21103#discussion_r205668821).
1. Generate optimized code for all of the primitive types except `boolean`
1. Generate code using `ArrayBuilder` or `ArrayBuffer`
1. Leave only a generic path in the interpreted path

## What changes were proposed in this pull request?
Currently the Structured Streaming sources and sinks does not have a way to report custom metrics. Providing an option to report custom metrics and making it available via Streaming Query progress can enable sources and sinks to report custom progress information (E.g. the lag metrics for Kafka source).
Similar metrics can be reported for Sinks as well, but would like to get initial feedback before proceeding further.
## How was this patch tested?
New and existing unit tests.

## What changes were proposed in this pull request?
Currently, debug package has a implicit class "DebugQuery" which matches Dataset to provide debug features on Dataset class. 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.

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.

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.
