The current use of `withSQLConf` in `ParquetSchemaPruningSuite.scala` is incorrect. The desired configuration settings are not being set when running the test cases.

Fixes the collision issue with spark executor names in client mode, see SPARK-25295 for the details.
It follows the cluster name convention as app-name will be used as the prefix and if that is not defined we use "spark" as the default prefix. Eg. `spark-pi-1536781360723-exec-1` where spark-pi is the name of the app passed at the config side or transformed if it contains illegal characters.
Also fixes the issue with spark app name having spaces in cluster mode.
If you run the Spark Pi test in client mode it passes.
The tricky part is the user may set the app name:
3030b82c89/examples/src/main/scala/org/apache/spark/examples/SparkPi.scala (L30)
If i do:
```
./bin/spark-submit
...
--deploy-mode cluster --name "spark pi"
...
```
it will fail as the app name is used for the prefix of driver's pod name and it cannot have spaces (according to k8s conventions).
## How was this patch tested?

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

Field metadata removed from SparkPlanInfo in #18600 . Corresponding, many meta data was also removed from event SparkListenerSQLExecutionStart in Spark event log. If we want to analyze event log to get all input paths, we couldn't get them. Instead, simpleString of SparkPlanInfo JSON only display 100 characters, it won't help.
Before 2.3, the fragment of SparkListenerSQLExecutionStart in event log looks like below (It contains the metadata field which has the intact information):
>{"Event":"org.apache.spark.sql.execution.ui.SparkListenerSQLExecutionStart", Location: InMemoryFileIndex[hdfs://cluster1/sys/edw/test1/test2/test3/test4..., "metadata": {"Location": "InMemoryFileIndex[hdfs://cluster1/sys/edw/test1/test2/test3/test4/test5/snapshot/dt=20180904]","ReadSchema":"struct<snpsht_start_dt:date,snpsht_end_dt:date,am_ntlogin_name:string,am_first_name:string,am_last_name:string,isg_name:string,CRE_DATE:date,CRE_USER:string,UPD_DATE:timestamp,UPD_USER:string>"}
After #18600, metadata field was removed.
>{"Event":"org.apache.spark.sql.execution.ui.SparkListenerSQLExecutionStart", Location: InMemoryFileIndex[hdfs://cluster1/sys/edw/test1/test2/test3/test4...,
So I add this field back to SparkPlanInfo class. Then it will log out the meta data to event log. Intact information in event log is very useful for offline job analysis.

Schema pruning doesn't work if nested column is used in where clause.
For example,
```
sql("select name.first from contacts where name.first = 'David'")
== Physical Plan ==
*(1) Project [name#19.first AS first#40]
+- *(1) Filter (isnotnull(name#19) && (name#19.first = David))
+- *(1) FileScan parquet [name#19] Batched: false, Format: Parquet, PartitionFilters: [],
PushedFilters: [IsNotNull(name)], ReadSchema: struct<name:struct<first:string,middle:string,last:string>>
```
In above query plan, the scan node reads the entire schema of `name` column.
This issue is reported by:
https://github.com/apache/spark/pull/21320#issuecomment-419290197
The cause is that we infer a root field from expression `IsNotNull(name)`. However, for such expression, we don't really use the nested fields of this root field, so we can ignore the unnecessary nested fields.

## What changes were proposed in this pull request?
We will update block info coming from executors, at the timing like caching a RDD. However, when removing RDDs with unpersisting, we don't ask to update block info. So the block info is not updated.
We can fix this with few options:
1. Ask to update block info when unpersisting
This is simplest but changes driver-executor communication a bit.
2. Update block info when processing the event of unpersisting RDD
We send a `SparkListenerUnpersistRDD` event when unpersisting RDD. When processing this event, we can update block info of the RDD. This only changes event processing code so the risk seems to be lower.
Currently this patch takes option 2 for lower risk. If we agree first option has no risk, we can change to it.

## What changes were proposed in this pull request?
In the Planner, we collect the placeholder which need to be substituted in the query execution plan and once we plan them, we substitute the placeholder with the effective plan.
In this second phase, we rely on the `==` comparison, ie. the `equals` method. This means that if two placeholder plans - which are different instances - have the same attributes (so that they are equal, according to the equal method) they are both substituted with their corresponding new physical plans. So, in such a situation, the first time we substitute both them with the first of the 2 new generated plan and the second time we substitute nothing.
This is usually of no harm for the execution of the query itself, as the 2 plans are identical. But since they are the same instance, now, the local variables are shared (which is unexpected). This causes issues for the metrics collected, as the same node is executed 2 times, so the metrics are accumulated 2 times, wrongly.
The PR proposes to use the `eq` method in checking which placeholder needs to be substituted,; thus in the previous situation, actually both the two different physical nodes which are created (one for each time the logical plan appears in the query plan) are used and the metrics are collected properly for each of them.

Apache Spark doesn't create Hive table with duplicated fields in both case-sensitive and case-insensitive mode. However, if Spark creates ORC files in case-sensitive mode first and create Hive table on that location, where it's created. In this situation, field resolution should fail in case-insensitive mode. Otherwise, we don't know which columns will be returned or filtered. Previously, SPARK-25132 fixed the same issue in Parquet.
Here is a simple example:
```
val data = spark.range(5).selectExpr("id as a", "id * 2 as A")
spark.conf.set("spark.sql.caseSensitive", true)
data.write.format("orc").mode("overwrite").save("/user/hive/warehouse/orc_data")
sql("CREATE TABLE orc_data_source (A LONG) USING orc LOCATION '/user/hive/warehouse/orc_data'")
spark.conf.set("spark.sql.caseSensitive", false)
sql("select A from orc_data_source").show
+---+
| A|
+---+
| 3|
| 2|
| 4|
| 1|
| 0|
+---+

CREATE VIEW testview AS SELECT d100.udf100(name) FROM default.emp;
```
**Spark:**
```
sql("SELECT * FROM testview").show()
```
```
scala> sql("SELECT * FROM testview").show()
org.apache.spark.sql.AnalysisException: Undefined function: 'd100.udf100'. This function is neither a registered temporary function nor a permanent function registered in the database 'default'.; line 1 pos 7
```
Under the hood, it actually makes sense since the view is defined as `SELECT d100.udf100(name) FROM default.emp;` and Hive API:
```
org.apache.hadoop.hive.ql.metadata.Table.getViewExpandedText()
```
This returns a wrongly qualified SQL string for the view as below:
```
SELECT `d100.udf100`(`emp`.`name`) FROM `default`.`emp`
```
which works fine in Hive but not in Spark.
## How was this patch tested?
Manually:
```
18/09/06 19:32:48 DEBUG HiveSessionCatalog: 'SELECT `d100.udf100`(`emp`.`name`) FROM `default`.`emp`' will be used for the view(testview).
```

Add new executor level memory metrics (JVM used memory, on/off heap execution memory, on/off heap storage memory, on/off heap unified memory, direct memory, and mapped memory), and expose via the executors REST API. This information will help provide insight into how executor and driver JVM memory is used, and for the different memory regions. It can be used to help determine good values for spark.executor.memory, spark.driver.memory, spark.memory.fraction, and spark.memory.storageFraction.
## What changes were proposed in this pull request?
An ExecutorMetrics class is added, with jvmUsedHeapMemory, jvmUsedNonHeapMemory, onHeapExecutionMemory, offHeapExecutionMemory, onHeapStorageMemory, and offHeapStorageMemory, onHeapUnifiedMemory, offHeapUnifiedMemory, directMemory and mappedMemory. The new ExecutorMetrics is sent by executors to the driver as part of the Heartbeat. A heartbeat is added for the driver as well, to collect these metrics for the driver.
The EventLoggingListener store information about the peak values for each metric, per active stage and executor. When a StageCompleted event is seen, a StageExecutorsMetrics event will be logged for each executor, with peak values for the stage.
The AppStatusListener records the peak values for each memory metric.
The new memory metrics are added to the executors REST API.
## How was this patch tested?
New unit tests have been added. This was also tested on our cluster.

Add [flake8](http://flake8.pycqa.org) tests to find Python syntax errors and undefined names.
__E901,E999,F821,F822,F823__ are the "_showstopper_" flake8 issues that can halt the runtime with a SyntaxError, NameError, etc. Most other flake8 issues are merely "style violations" -- useful for readability but they do not effect runtime safety.
* F821: undefined name `name`
* F822: undefined name `name` in `__all__`
* F823: local variable name referenced before assignment
* E901: SyntaxError or IndentationError
* E999: SyntaxError -- failed to compile a file into an Abstract Syntax Tree

## What changes were proposed in this pull request?
Before Apache Spark 2.3, table properties were ignored when writing data to a hive table(created with STORED AS PARQUET/ORC syntax), because the compression configurations were not passed to the FileFormatWriter in hadoopConf. Then it was fixed in #20087. But actually for CTAS with USING PARQUET/ORC syntax, table properties were ignored too when convertMastore, so the test case for CTAS not supported.
Now it has been fixed in #20522 , the test case should be enabled too.
## How was this patch tested?
This only re-enables the test cases of previous PR.

## What changes were proposed in this pull request?
This pr removed the method `updateBytesReadWithFileSize` in `FileScanRDD` because it computes input metrics by file size supported in Hadoop 2.5 and earlier. The current Spark does not support the versions, so it causes wrong input metric numbers.
This is rework from #22232.
