[SPARK-14837][SQL][STREAMING] Added support in file stream source for reading new files added to subdirs

## What changes were proposed in this pull request?
Currently, file stream source can only find new files if they appear in the directory given to the source, but not if they appear in subdirs. This PR add support for providing glob patterns when creating file stream source so that it can find new files in nested directories based on the glob pattern.

## How was this patch tested?

Unit test that tests when new files are discovered with globs and partitioned directories.

## What changes were proposed in this pull request?

FlumePollingStreamSuite contains two tests which run for a minute each. This seems excessively slow and we should speed it up if possible.

In this PR, instead of creating `StreamingContext` directly from `conf`, here an underlying `SparkContext` is created before all and it is used to create  each`StreamingContext`.

Running time is reduced by avoiding multiple `SparkContext` creations and destroys.

## How was this patch tested?

Tested on my local machine running `testOnly *.FlumePollingStreamSuite`

Because this test extracts data from `DStream.generatedRDDs` before stopping, it may get data before checkpointing. Then after recovering from the checkpoint, `recoveredOffsetRanges` may contain something not in `offsetRangesBeforeStop`, which will fail the test. Adding `Thread.sleep(1000)` before `ssc.stop()` will reproduce this failure.

This PR just moves the logic of `offsetRangesBeforeStop` (also renamed to `offsetRangesAfterStop`) after `ssc.stop()` to fix the flaky test.

Currently, Java Linter is disabled in Jenkins tests.

However, as of today, Spark has 721 java files with 97362 code (without blank/comments). It's about 1/3 of Scala.

This PR aims to take advantage of Travis CI to handle the following static analysis by adding a single file, `.travis.yml` without any additional burden on the existing servers.

- Java Linter
- JDK7/JDK8 maven compile

Note that this PR does not propose to remove some of the above work items from the Jenkins. It's possible, but we need to observe the Travis CI stability for a while. The main goal of this issue is to remove committer's overhead on linter-related PRs (the original PR and the fixation PR).

## What changes were proposed in this pull request?
A Generate with the `outer` flag enabled should always return one or more rows for every input row. The optimizer currently violates this by rewriting `outer` Generates that do not contain columns of the child plan into an unjoined generate, for example:
```sql
select e from a lateral view outer explode(a.b) as e
```
The result of this is that `outer` Generate does not produce output at all when the Generators' input expression is empty. This PR fixes this.

Since we cannot really trust if the underlying external catalog can throw exceptions when there is an invalid metadata operation, let's do it in SessionCatalog.

- [X] The first step is to unify the error messages issued in Hive-specific Session Catalog and general Session Catalog.
- [X] The second step is to verify the inputs of metadata operations for partitioning-related operations. This is moved to a separate PR: https://github.com/apache/spark/pull/12801
- [X] The third step is to add database existence verification in `SessionCatalog`
- [X] The fourth step is to add table existence verification in `SessionCatalog`

Without this, the code would build an invalid spark-submit command line,
and a more cryptic error would be presented to the user. Also, expose
a constant that allows users to set a dummy resource in cases where
they don't need an actual resource file; for backwards compatibility,
that uses the same "spark-internal" resource that Spark itself uses.

Tested via unit tests, run-example, spark-shell, and running the
thrift server with mixed spark and hive command line arguments.

bash doesn't really propagate errors from subshells when using redirection
the way spark-class does; so, instead, this change captures the exit code
of the launcher process in the command array, and checks it before executing
the actual command.

Tested by injecting an error in Main.java (the launcher entry point) and
verifying the shell gets the right exit code from spark-class.

[SPARK-14127][SQL] "DESC <table>": Extracts schema information from table properties for data source tables

## What changes were proposed in this pull request?

This is a follow-up of #12934 and #12844. This PR adds a set of utility methods in `DDLUtils` to help extract schema information (user-defined schema, partition columns, and bucketing information) from data source table properties. These utility methods are then used in `DescribeTableCommand` to refine output for data source tables. Before this PR, the aforementioned schema information are only shown as table properties, which are hard to read.

Currently PipedRDD internally uses PrintWriter to write data to the stdin of the piped process, which by default uses a BufferedWriter of buffer size 8k. In our experiment, we have seen that 8k buffer size is too small and the job spends significant amount of CPU time in system calls to copy the data. We should have a way to configure the buffer size for the writer.

This PR is to address a few existing issues in `EXPLAIN`:
- The `EXPLAIN` options `LOGICAL | FORMATTED | EXTENDED | CODEGEN` should not be 0 or more match. It should 0 or one match. Parser does not allow users to use more than one option in a single command.
- The option `LOGICAL` is not supported. Issue an exception when users specify this option in the command.
- The output of `EXPLAIN ` contains a weird empty line when the output of analyzed plan is empty. We should remove it. For example:
  ```
  == Parsed Logical Plan ==
  CreateTable CatalogTable(`t`,CatalogTableType(MANAGED),CatalogStorageFormat(None,Some(org.apache.hadoop.mapred.TextInputFormat),Some(org.apache.hadoop.hive.ql.io.

## What changes were proposed in this pull request?
Our case sensitivity support is different from what ANSI SQL standards support. Postgres' behavior is that if an identifier is quoted, then it is treated as case sensitive; otherwise it is folded to lowercase. We will likely need to revisit this in the future and change our behavior. For now, the safest change to do for Spark 2.0 is to make the case sensitive option internal and discourage users from turning it on, effectively making Spark always case insensitive.

## What changes were proposed in this pull request?
The issue is that when the user provides the path option with uppercase "PATH" key, `options` contains `PATH` key and will get into the non-external case in the following code in `createDataSourceTables.scala`, where a new key "path" is created with a default path.
```
val optionsWithPath =
      if (!options.contains("path")) {
        isExternal = false
        options + ("path" -> sessionState.catalog.defaultTablePath(tableIdent))
      } else {
        options
      }
```
So before creating hive table, serdeInfo.parameters will contain both "PATH" and "path" keys and different directories. and Hive table's dataLocation contains the value of "path".

The fix in this PR is to convert `options` in the code above to `CaseInsensitiveMap` before checking for containing "path" key.

sc.setJobDescription("single quote: ' ")
sc.parallelize(1 to 10).count()
```

and then browsing to the driver UI. Previously, this resulted in an "Uncaught SyntaxError" because the single quote from the description was not escaped and ended up closing a Javascript string literal too early.

The fix implemented here is to change the relevant Javascript to define its string literals using double-quotes. Our escaping logic already properly escapes double quotes in the description, so this is safe to do.

## How was this patch tested?

Tested manually in `spark-shell` using the following cases:

```scala
sc.setJobDescription("double quote: \" ")
sc.parallelize(1 to 10).count()

sc.setJobDescription("single quote: ' ")
sc.parallelize(1 to 10).count()

sc.setJobDescription("ampersand: &")
sc.parallelize(1 to 10).count()

sc.setJobDescription("newline: \n text after newline ")
sc.parallelize(1 to 10).count()

sc.setJobDescription("carriage return: \r text after return ")
sc.parallelize(1 to 10).count()
```

Closes #12995 from JoshRosen/SPARK-15209.

This patch improves the performance of `InferSchema.compatibleType` and `inferField`. The net result of this patch is a 6x speedup in local benchmarks running against cached data with a massive nested schema.

The key idea is to remove unnecessary sorting in `compatibleType`'s `StructType` merging code. This code takes two structs, merges the fields with matching names, and copies over the unique fields, producing a new schema which is the union of the two structs' schemas. Previously, this code performed a very inefficient `groupBy()` to match up fields with the same name, but this is unnecessary because `inferField` already sorts structs' fields by name: since both lists of fields are sorted, we can simply merge them in a single pass.

This patch also speeds up the existing field sorting in `inferField`: the old sorting code allocated unnecessary intermediate collections, while the new code uses mutable collects and performs in-place sorting.

I rewrote inefficient `equals()` implementations in `StructType` and `Metadata`, significantly reducing object allocations in those methods.

Finally, I replaced a `treeAggregate` call with `fold`: I doubt that `treeAggregate` will benefit us very much because the schemas would have to be enormous to realize large savings in network traffic. Since most schemas are probably fairly small in serialized form, they should typically fit within a direct task result and therefore can be incrementally merged at the driver as individual tasks finish. This change eliminates an entire (short) scheduler stage.

When we parse `CREATE TABLE USING`, we should build a `CreateTableUsing` plan with the `managedIfNoPath` set to true. Then we will add default table path to options when write it to hive.
