If users set equivalent values to spark.network.timeout and spark.executor.heartbeatInterval, they get the following message:
```
java.lang.IllegalArgumentException: requirement failed: The value of spark.network.timeout=120s must be no less than the value of spark.executor.heartbeatInterval=120s.
```
But it's misleading since it can be read as they could be equal. So this PR replaces "no less than" with "greater than". Also, it fixes similar inconsistencies found in MLlib and SQL components.
## How was this patch tested?
Ran Spark with equivalent values for them manually and confirmed that the revised message was displayed.

Fix race condition where streams can have unexpected conf values.
New streaming queries should run with isolated SparkSessions so that they aren't affected by conf updates after they are started. In StreamExecution, the parent SparkSession is cloned and used to run each batch, but this cloning happens in a separate thread and may happen after DataStreamWriter.start() returns. If a stream is started and a conf key is set immediately after, the stream is likely to have the new value.
## How was this patch tested?

With Scala-2.12 profile, Spark application fails while Spark is okay.

In https://github.com/apache/spark/pull/23043 , we introduced a behavior change: Spark users are not able to distinguish 0.0 and -0.0 anymore.
This PR proposes an alternative fix to the original bug, to retain the difference between 0.0 and -0.0 inside Spark.
The idea is, we can rewrite the window partition key, join key and grouping key during logical phase, to normalize the special floating numbers. Thus only operators care about special floating numbers need to pay the perf overhead, and end users can distinguish -0.0.

## What changes were proposed in this pull request?
During the follow-up work(#23435) for PySpark worker reuse scenario, we found that the worker reuse takes no effect for `sc.parallelize(xrange(...))`. It happened because of the specialize rdd.parallelize logic for xrange(introduced in #3264) generated data by lazy iterable range, which don't need to use the passed-in iterator. But this will break the end of stream checking in python worker and finally cause worker reuse takes no effect. See more details in [SPARK-26549](https://issues.apache.org/jira/browse/SPARK-26549) description.
We fix this by force using the passed-in iterator.

Currently Spark table maintains Hive catalog storage format, so that Hive client can read it. In `HiveSerDe.scala`, Spark uses a mapping from its data source to HiveSerde. The mapping is old, we need to update with latest canonical name of Parquet and Orc FileFormat.
Otherwise the following queries will result in wrong Serde value in Hive table(default value `org.apache.hadoop.mapred.SequenceFileInputFormat`), and Hive client will fail to read the output table:
```
df.write.format("org.apache.spark.sql.execution.datasources.parquet.ParquetFileFormat").saveAsTable(..)
```
```
df.write.format("org.apache.spark.sql.execution.datasources.orc.OrcFileFormat").saveAsTable(..)

Spark always creates secure py4j connections between java and python,
but it also allows users to pass in their own connection. This ensures
that even passed in connections are secure.
Added test cases verifying the failure with a (mocked) insecure gateway.
This is closely related to SPARK-26019, but this entirely forbids the
insecure connection, rather than creating the "escape-hatch".

## What changes were proposed in this pull request?
Introducing shared polled ByteBuf allocators.
This feature can be enabled via the "spark.network.sharedByteBufAllocators.enabled" configuration.
When it is on then only two pooled ByteBuf allocators are created:
- one for transport servers where caching is allowed and
- one for transport clients where caching is disabled
This way the cache allowance remains as before.
Both shareable pools are created with numCores parameter set to 0 (which defaults to the available processors) as conf.serverThreads() and conf.clientThreads() are module dependant and the lazy creation of this allocators would lead to unpredicted behaviour.
When "spark.network.sharedByteBufAllocators.enabled" is false then a new allocator is created for every transport client and server separately as was before this PR.

Currently there is code scattered in a bunch of places to do different
things related to HTTP security, such as access control, setting
security-related headers, and filtering out bad content. This makes it
really easy to miss these things when writing new UI code.
This change creates a new filter that does all of those things, and
makes sure that all servlet handlers that are attached to the UI get
the new filter and any user-defined filters consistently. The extent
of the actual features should be the same as before.
The new filter is added at the end of the filter chain, because authentication
is done by custom filters and thus needs to happen first. This means that
custom filters see unfiltered HTTP requests - which is actually the current
behavior anyway.
As a side-effect of some of the code refactoring, handlers added after
the initial set also get wrapped with a GzipHandler, which didn't happen
before.
Tested with added unit tests and in a history server with SPNEGO auth
configured.

## What changes were proposed in this pull request?
The existing query hint implementation relies on a logical plan node `ResolvedHint` to store query hints in logical plans, and on `Statistics` in physical plans. Since `ResolvedHint` is not really a logical operator and can break the pattern matching for existing and future optimization rules, it is a issue to the Optimizer as the old `AnalysisBarrier` was to the Analyzer.
Given the fact that all our query hints are either 1) a join hint, i.e., broadcast hint; or 2) a re-partition hint, which is indeed an operator, we only need to add a hint field on the Join plan and that will be a good enough solution for the current hint usage.
This PR is to let `Join` node have a hint for its left sub-tree and another hint for its right sub-tree and each hint is a merged result of all the effective hints specified in the corresponding sub-tree. The "effectiveness" of a hint, i.e., whether that hint should be propagated to the `Join` node, is currently consistent with the hint propagation rules originally implemented in the `Statistics` approach. Note that the `ResolvedHint` node still has to live through the analysis stage because of the `Dataset` interface, but it will be got rid of and moved to the `Join` node in the "pre-optimization" stage.
This PR also introduces a change in how hints work with join reordering. Before this PR, hints would stop join reordering. For example, in "a.join(b).join(c).hint("broadcast").join(d)", the broadcast hint would stop d from participating in the cost-based join reordering while still allowing reordering from under the hint node. After this PR, though, the broadcast hint will not interfere with join reordering at all, and after reordering if a relation associated with a hint stays unchanged or equivalent to the original relation, the hint will be retained, otherwise will be discarded. For example, the original plan is like "a.join(b).hint("broadcast").join(c).hint("broadcast").join(d)", thus the join order is "a JOIN b JOIN c JOIN d". So if after reordering the join order becomes "a JOIN b JOIN (c JOIN d)", the plan will be like "a.join(b).hint("broadcast").join(c.join(d))"; but if after reordering the join order becomes "a JOIN c JOIN b JOIN d", the plan will be like "a.join(c).join(b).hint("broadcast").join(d)".

This change modifies the behavior of the delegation token code when running
on YARN, so that the driver controls the renewal, in both client and cluster
mode. For that, a few different things were changed:
* The AM code only runs code that needs DTs when DTs are available.
In a way, this restores the AM behavior to what it was pre-SPARK-23361, but
keeping the fix added in that bug. Basically, all the AM code is run in a
"UGI.doAs()" block; but code that needs to talk to HDFS (basically the
distributed cache handling code) was delayed to the point where the driver
is up and running, and thus when valid delegation tokens are available.
* SparkSubmit / ApplicationMaster now handle user login, not the token manager.
The previous AM code was relying on the token manager to keep the user
logged in when keytabs are used. This required some odd APIs in the token
manager and the AM so that the right UGI was exposed and used in the right
places.
After this change, the logged in user is handled separately from the token
manager, so the API was cleaned up, and, as explained above, the whole AM
runs under the logged in user, which also helps with simplifying some more code.
* Distributed cache configs are sent separately to the AM.
Because of the delayed initialization of the cached resources in the AM, it
became easier to write the cache config to a separate properties file instead
of bundling it with the rest of the Spark config. This also avoids having
to modify the SparkConf to hide things from the UI.
* Finally, the AM doesn't manage the token manager anymore.
The above changes allow the token manager to be completely handled by the
driver's scheduler backend code also in YARN mode (whether client or cluster),
making it similar to other RMs. To maintain the fix added in SPARK-23361 also
in client mode, the AM now sends an extra message to the driver on initialization
to fetch delegation tokens; and although it might not really be needed, the
driver also keeps the running AM updated when new tokens are created.
Tested in a kerberized cluster with the same tests used to validate SPARK-23361,
in both client and cluster mode. Also tested with a non-kerberized cluster.

My pull request #23288 was resolved and merged to master, but it turned out later that my change breaks another regression test. Because we cannot reopen pull request, I create a new pull request here.
Commit 92934b4 is only change after pull request #23288.
`CheckFileExist` was avoided at 239cfa4 after discussing #23288 (comment).
But, that change turned out to be wrong because we should not check if argument checkFileExist is false.
Test 27e42c1de5/sql/core/src/test/scala/org/apache/spark/sql/SQLQuerySuite.scala (L2555)
failed when we avoided checkFileExist, but now successed after commit 92934b4 .

## What changes were proposed in this pull request?
Address SPARK-26548, in Spark 2.4.0, the CacheManager holds a write lock while computing the executedPlan for a cached logicalPlan. In some cases with very large query plans this can be an expensive operation, taking minutes to run. The entire cache is blocked during this time. This PR changes that so the writeLock is only obtained after the executedPlan is generated, this reduces the time the lock is held to just the necessary time when the shared data structure is being updated.
gatorsmile and cloud-fan - You can committed patches in this area before. This is a small incremental change.
## How was this patch tested?
Has been tested on a live system where the blocking was causing major issues and it is working well.
CacheManager has no explicit unit test but is used in many places internally as part of the SharedState.
