User specified filters are not applied to SQL tab in yarn mode, as it is overridden by the yarn AmIp filter.
So we need to append user provided filters (spark.ui.filters) with yarn filter.
## How was this patch tested?
【Test step】：
1) Launch spark sql with authentication filter as below:
2) spark-sql --master yarn --conf spark.ui.filters=org.apache.hadoop.security.authentication.server.AuthenticationFilter --conf spark.org.apache.hadoop.security.authentication.server.AuthenticationFilter.params="type=simple"
3) Go to Yarn application list UI link
4) Launch the application master for the Spark-SQL app ID and access all the tabs by appending tab name.
5) It will display an error for all tabs including SQL tab.(before able to access SQL tab,as Authentication filter is not applied for SQL tab)
6) Also can be verified with info logs,that Authentication filter applied to SQL tab.(before it is not applied).
I have attached the behaviour below in following order..
1) Command used
2) Before fix (logs and UI)
3) After fix (logs and UI)
**1) COMMAND USED**:
launching spark-sql with authentication filter.
**2) BEFORE FIX:**
**UI result:**
able to access SQL tab.
**logs**:
authentication filter not applied to SQL tab.
**3) AFTER FIX:**
**UI result**:
Not able to access SQL tab.
**in logs**:
Both yarn filter and Authentication filter applied to SQL tab.

Add a trait HasTrainingSummary to avoid code duplicate related to training summary.
Currently all the training summary use the similar pattern which can be generalized,
```
private[ml] final var trainingSummary: Option[T] = None
def hasSummary: Boolean = trainingSummary.isDefined
def summary: T = trainingSummary.getOrElse...
private[ml] def setSummary(summary: Option[T]): ...
```
Classes with the trait need to override `setSummry`. And for Java compatibility, they will also have to override `summary` method, otherwise the java code will regard all the summary class as Object due to a known issue with Scala.

## What changes were proposed in this pull request?
The optimizer rule `org.apache.spark.sql.catalyst.optimizer.ReorderJoin` performs join reordering on inner joins. This was introduced from SPARK-12032 (https://github.com/apache/spark/pull/10073) in 2015-12.
After it had reordered the joins, though, it didn't check whether or not the output attribute order is still the same as before. Thus, it's possible to have a mismatch between the reordered output attributes order vs the schema that a DataFrame thinks it has.
The same problem exists in the CBO version of join reordering (`CostBasedJoinReorder`) too.
This can be demonstrated with the example:
```scala
spark.sql("create table table_a (x int, y int) using parquet")
spark.sql("create table table_b (i int, j int) using parquet")
spark.sql("create table table_c (a int, b int) using parquet")
val df = spark.sql("""
with df1 as (select * from table_a cross join table_b)
select * from df1 join table_c on a = x and b = i
""")
```
here's what the DataFrame thinks:
```
scala> df.printSchema
root
|-- x: integer (nullable = true)
|-- y: integer (nullable = true)
|-- i: integer (nullable = true)
|-- j: integer (nullable = true)
|-- a: integer (nullable = true)
|-- b: integer (nullable = true)
```
here's what the optimized plan thinks, after join reordering:
```
scala> df.queryExecution.optimizedPlan.output.foreach(a => println(s"|-- ${a.name}: ${a.dataType.typeName}"))
|-- x: integer
|-- y: integer
|-- a: integer
|-- b: integer
|-- i: integer
|-- j: integer
```
If we exclude the `ReorderJoin` rule (using Spark 2.4's optimizer rule exclusion feature), it's back to normal:
```
scala> spark.conf.set("spark.sql.optimizer.excludedRules", "org.apache.spark.sql.catalyst.optimizer.ReorderJoin")
scala> val df = spark.sql("with df1 as (select * from table_a cross join table_b) select * from df1 join table_c on a = x and b = i")
df: org.apache.spark.sql.DataFrame = [x: int, y: int ... 4 more fields]
scala> df.queryExecution.optimizedPlan.output.foreach(a => println(s"|-- ${a.name}: ${a.dataType.typeName}"))
|-- x: integer
|-- y: integer
|-- i: integer
|-- j: integer
|-- a: integer
|-- b: integer
```
Note that this output attribute ordering problem leads to data corruption, and can manifest itself in various symptoms:
* Silently corrupting data, if the reordered columns happen to either have matching types or have sufficiently-compatible types (e.g. all fixed length primitive types are considered as "sufficiently compatible" in an `UnsafeRow`), then only the resulting data is going to be wrong but it might not trigger any alarms immediately. Or
* Weird Java-level exceptions like `java.lang.NegativeArraySizeException`, or even SIGSEGVs.
## How was this patch tested?
Added new unit test in `JoinReorderSuite` and new end-to-end test in `JoinSuite`.
Also made `JoinReorderSuite` and `StarJoinReorderSuite` assert more strongly on maintaining output attribute order.

Multiple SparkContexts are discouraged and it has been warning for last 4 years, see SPARK-4180. It could cause arbitrary and mysterious error cases, see SPARK-2243.

When Kafka delegation token obtained, SCRAM `sasl.mechanism` has to be configured for authentication. This can be configured on the related source/sink which is inconvenient from user perspective. Such granularity is not required and this configuration can be implemented with one central parameter.
In this PR `spark.kafka.sasl.token.mechanism` added to configure this centrally (default: `SCRAM-SHA-512`).

## What changes were proposed in this pull request?
YARN applicationMaster metrics registration introduced in SPARK-24594 causes further registration of static metrics (Codegenerator and HiveExternalCatalog) and of JVM metrics, which I believe do not belong in this context.
This looks like an unintended side effect of using the start method of [[MetricsSystem]].
A possible solution proposed here, is to introduce startNoRegisterSources to avoid these additional registrations of static sources and of JVM sources in the case of YARN applicationMaster metrics (this could be useful for other metrics that may be added in the future).
## How was this patch tested?
Manually tested on a YARN cluster,

This change makes the driver and executor builders a lot simpler
by encapsulating almost all feature logic into the respective
feature classes. The only logic that remains is the creation of
the initial pod, which needs to happen before anything else so
is better to be left in the builder class.
Most feature classes already behave fine when the config has nothing
they should handle, but a few minor tweaks had to be added. Unit
tests were also updated or added to account for these.
The builder suites were simplified a lot and just test the remaining
pod-related code in the builders themselves.

The evaluators BinaryClassificationEvaluator, RegressionEvaluator, and MulticlassClassificationEvaluator and the corresponding metrics classes BinaryClassificationMetrics, RegressionMetrics and MulticlassMetrics should use sample weight data.
I've closed the PR: https://github.com/apache/spark/pull/16557
as recommended in favor of creating three pull requests, one for each of the evaluators (binary/regression/multiclass) to make it easier to review/update.
The updates to the regression metrics were based on (and updated with new changes based on comments):
https://issues.apache.org/jira/browse/SPARK-11520
("RegressionMetrics should support instance weights")
but the pull request was closed as the changes were never checked in.
## How was this patch tested?

This proposes an alternative way to load secret keys into a Spark application that is running on Kubernetes. Instead of automatically generating the secret, the secret key can reside in a file that is shared between both the driver and executor containers.

## What changes were proposed in this pull request?
In `BytesToBytesMap.MapIterator.advanceToNextPage`, We will first lock this `MapIterator` and then `TaskMemoryManager` when going to free a memory page by calling `freePage`. At the same time, it is possibly that another memory consumer first locks `TaskMemoryManager` and then this `MapIterator` when it acquires memory and causes spilling on this `MapIterator`.
So it ends with the `MapIterator` object holds lock to the `MapIterator` object and waits for lock on `TaskMemoryManager`, and the other consumer holds lock to `TaskMemoryManager` and waits for lock on the `MapIterator` object.
To avoid deadlock here, this patch proposes to keep reference to the page to free and free it after releasing the lock of `MapIterator`.
## How was this patch tested?
Added test and manually test by running the test 100 times to make sure there is no deadlock.

In the PR, I propose to return partial results from JSON datasource and JSON functions in the PERMISSIVE mode if some of JSON fields are parsed and converted to desired types successfully. The changes are made only for `StructType`. Whole bad JSON records are placed into the corrupt column specified by the `columnNameOfCorruptRecord` option or SQL config.
Partial results are not returned for malformed JSON input.
## How was this patch tested?
Added new UT which checks converting JSON strings with one invalid and one valid field at the end of the string.

This is a regression introduced by https://github.com/apache/spark/pull/22104 at Spark 2.4.0.
When we have Python UDF in subquery, we will hit an exception
```
Caused by: java.lang.ClassCastException: org.apache.spark.sql.catalyst.expressions.AttributeReference cannot be cast to org.apache.spark.sql.catalyst.expressions.PythonUDF
at scala.collection.immutable.Stream.map(Stream.scala:414)

```
https://github.com/apache/spark/pull/22104 turned `ExtractPythonUDFs` from a physical rule to optimizer rule. However, there is a difference between a physical rule and optimizer rule. A physical rule always runs once, an optimizer rule may be applied twice on a query tree even the rule is located in a batch that only runs once.
For a subquery, the `OptimizeSubqueries` rule will execute the entire optimizer on the query plan inside subquery. Later on subquery will be turned to joins, and the optimizer rules will be applied to it again.
Unfortunately, the `ExtractPythonUDFs` rule is not idempotent. When it's applied twice on a query plan inside subquery, it will produce a malformed plan. It extracts Python UDF from Python exec plans.
This PR proposes 2 changes to be double safe:
1. `ExtractPythonUDFs` should skip python exec plans, to make the rule idempotent
2. `ExtractPythonUDFs` should skip subquery

This adds the entire memory used by spark’s executor (as measured by procfs) to the executor metrics. The memory usage is collected from the entire process tree under the executor. The metrics are subdivided into memory used by java, by python, and by other processes, to aid users in diagnosing the source of high memory usage.
The additional metrics are sent to the driver in heartbeats, using the mechanism introduced by SPARK-23429. This also slightly extends that approach to allow one ExecutorMetricType to collect multiple metrics.
Added unit tests and also tested on a live cluster.
