When deserializing values of ArrayType with struct elements in java beans, fields of structs get mixed up.
I suggest using struct data types retrieved from resolved input data instead of inferring them from java beans.
## What changes were proposed in this pull request?
MapObjects expression is used to map array elements to java beans. Struct type of elements is inferred from java bean structure and ends up with mixed up field order.
I used UnresolvedMapObjects instead of MapObjects, which allows to provide element type for MapObjects during analysis based on the resolved input data, not on the java bean.
## How was this patch tested?
Added a test case.
Built complete project on travis.

## What changes were proposed in this pull request?
The SQL execution listener framework was created from scratch(see https://github.com/apache/spark/pull/9078). It didn't leverage what we already have in the spark listener framework, and one major problem is, the listener runs on the spark execution thread, which means a bad listener can block spark's query processing.
This PR re-implements the SQL execution listener framework. Now `ExecutionListenerManager` is just a normal spark listener, which watches the `SparkListenerSQLExecutionEnd` events and post events to the
user-provided SQL execution listeners.

- Exposes several metrics regarding application status as a source, useful to scrape them via jmx instead of mining the metrics rest api. Example use case: prometheus + jmx exporter.
- Metrics are gathered when a job ends at the AppStatusListener side, could be more fine-grained but most metrics like tasks completed are also counted by executors. More metrics could be exposed in the future to avoid scraping executors in some scenarios.
- a config option `spark.app.status.metrics.enabled` is added to disable/enable these metrics, by default they are disabled.
This was manually tested with jmx source enabled and prometheus server on k8s:

AFAIK multi-column count is not widely supported by the mainstream databases(postgres doesn't support), and the SQL standard doesn't define it clearly, as near as I can tell.
Since Spark supports it, we should clearly document the current behavior and add tests to verify it.

Avro schema allows recursive reference, e.g. the schema for linked-list in https://avro.apache.org/docs/1.8.2/spec.html#schema_record
```
{
"type": "record",
"name": "LongList",
"aliases": ["LinkedLongs"], // old name for this
"fields" : [
{"name": "value", "type": "long"}, // each element has a long
{"name": "next", "type": ["null", "LongList"]} // optional next element
]
}
```
In current Spark SQL, it is impossible to convert the schema as `StructType` . Run `SchemaConverters.toSqlType(avroSchema)` and we will get stack overflow exception.
We should detect the recursive reference and throw exception for it.

Currently `Range` reports metrics in batch granularity. This is acceptable, but it's better if we can make it row granularity without performance penalty.
Before this PR, the metrics are updated when preparing the batch, which is before we actually consume data. In this PR, the metrics are updated after the data are consumed. There are 2 different cases:
1. The data processing loop has a stop check. The metrics are updated when we need to stop.
2. no stop check. The metrics are updated after the loop.

## What changes were proposed in this pull request?
This PR adds CLI support for YARN custom resources, e.g. GPUs and any other resources YARN defines.
The custom resources are defined with Spark properties, no additional CLI arguments were introduced.
The properties can be defined in the following form:
**AM resources, client mode:**
Format: `spark.yarn.am.resource.<resource-name>`
The property name follows the naming convention of YARN AM cores / memory properties: `spark.yarn.am.memory and spark.yarn.am.cores
`
**Driver resources, cluster mode:**
Format: `spark.yarn.driver.resource.<resource-name>`
The property name follows the naming convention of driver cores / memory properties: `spark.driver.memory and spark.driver.cores.`
**Executor resources:**
Format: `spark.yarn.executor.resource.<resource-name>`
The property name follows the naming convention of executor cores / memory properties: `spark.executor.memory / spark.executor.cores`.
For the driver resources (cluster mode) and executor resources properties, we use the `yarn` prefix here as custom resource types are specific to YARN, currently.
**Validation:**
Please note that a validation logic is added to avoid having requested resources defined in 2 ways, for example defining the following configs:
```
"--conf", "spark.driver.memory=2G",
"--conf", "spark.yarn.driver.resource.memory=1G"
```
will not start execution and will print an error message.
## How was this patch tested?
Unit tests + manual execution with Hadoop2 and Hadoop 3 builds.
Testing have been performed on a real cluster with Spark and YARN configured:
Cluster and client mode
Request Resource Types with lowercase and uppercase units
Start Spark job with only requesting standard resources (mem / cpu)
Error handling cases:
- Request unknown resource type
- Request Resource type (either memory / cpu) with duplicate configs at the same time (e.g. with this config:
```
--conf spark.yarn.am.resource.memory=1G \
--conf spark.yarn.driver.resource.memory=2G \
--conf spark.yarn.executor.resource.memory=3G \
```
), ResourceTypeValidator handles these cases well, so it is not permitted
- Request standard resource (memory / cpu) with the new style configs, e.g. --conf spark.yarn.am.resource.memory=1G, this is not permitted and handled well.
An example about how I ran the testcases:
```
cd ~;export HADOOP_CONF_DIR=/opt/hadoop/etc/hadoop/;
./spark-2.4.0-SNAPSHOT-bin-custom-spark/bin/spark-submit \
--class org.apache.spark.examples.SparkPi \
--master yarn \
--deploy-mode cluster \
--driver-memory 1G \
--driver-cores 1 \
--executor-memory 1G \
--executor-cores 1 \
--conf spark.logConf=true \
--conf spark.yarn.executor.resource.gpu=3G \
--verbose \

## What changes were proposed in this pull request?
When we enable event log compression and compression codec as 'zstd', we are unable to open the webui of the running application from the history server page.
The reason is that, Replay listener was unable to read from the zstd compressed eventlog due to the zstd frame was not finished yet. This causes truncated error while reading the eventLog.
So, when we try to open the WebUI from the History server page, it throws "truncated error ", and we never able to open running application in the webui, when we enable zstd compression.
In this PR, when the IO excpetion happens, and if it is a running application, we log the error,
"Failed to read Spark event log: evetLogDirAppName.inprogress", instead of throwing exception.
## How was this patch tested?
Test steps:
1)spark.eventLog.compress = true
2)spark.io.compression.codec = zstd
3)restart history server
4) launch bin/spark-shell
5) run some queries
6) Open history server page
7) click on the application

Many companies have their own enterprise GitHub to manage Spark code. To build and test in those repositories with Jenkins need to modify this script.
So I suggest to add some environment variables to allow regression testing in enterprise Jenkins instead of default Spark repository in GitHub.

Currently SQL tab in the WEBUI doesn't support pagination. Because of that following issues are happening.
1) For large number of executions, SQL page is throwing OOM exception (around 40,000)
2) For large number of executions, loading SQL page is taking time.
3) Difficult to analyse the execution table for large number of execution.
[Note: spark.sql.ui.retainedExecutions = 50000]
All the tabs, Jobs, Stages etc. supports pagination. So, to make it consistent with other tabs
SQL tab also should support pagination.
I have followed the similar flow of the pagination code in the Jobs and Stages page for SQL page.
Also, this patch doesn't make any behavior change for the SQL tab except the pagination support.
## How was this patch tested?
bin/spark-shell --conf spark.sql.ui.retainedExecutions=50000
Run 50,000 sql queries.

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.

Updated the original UT. This should be justified as the original UT became invalid after SPARK-25044.

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 */ }
```

1. Move `CSVDataSource.makeSafeHeader` to `CSVUtils.makeSafeHeader` (as is).
- Historically and at the first place of refactoring (which I did), I intended to put all CSV specific handling (like options), filtering, extracting header, etc.
- See `JsonDataSource`. Now `CSVDataSource` is quite consistent with `JsonDataSource`. Since CSV's code path is quite complicated, we might better match them as possible as we can.
2. Create `CSVHeaderChecker` and put `enforceSchema` logics into that.
- The checking header and column pruning stuff were added (per https://github.com/apache/spark/pull/20894 and https://github.com/apache/spark/pull/21296) but some of codes such as https://github.com/apache/spark/pull/22123 are duplicated
- Also, checking header code is basically here and there. We better put them in a single place, which was quite error-prone. See (https://github.com/apache/spark/pull/22656).
3. Move `CSVDataSource.checkHeaderColumnNames` to `CSVHeaderChecker.checkHeaderColumnNames` (as is).
- Similar reasons above with 1.

If the records are incremented by more than 1 at a time,the number of bytes might rarely ever get updated,because it might skip over the count that is an exact multiple of UPDATE_INPUT_METRICS_INTERVAL_RECORDS.
This PR just checks whether the increment causes the value to exceed a higher multiple of UPDATE_INPUT_METRICS_INTERVAL_RECORDS.
