This PR proposes to deprecate `register*` for UDFs in `SQLContext` and `Catalog` in Spark 2.3.0.
These are inconsistent with Scala / Java APIs and also these basically do the same things with `spark.udf.register*`.
Also, this PR moves the logcis from `[sqlContext|spark.catalog].register*` to `spark.udf.register*` and reuse the docstring.
This PR also handles minor doc corrections. It also includes https://github.com/apache/spark/pull/20158
## How was this patch tested?
Manually tested, manually checked the API documentation and tests added to check if deprecated APIs call the aliases correctly.

Hi all,
I would like to bump the PATCH versions of both the Apache httpclient Apache httpcore. I use the SparkTC Stocator library for connecting to an object store, and I would align the versions to reduce java version mismatches. Furthermore it is good to bump these versions since they fix stability and performance issues:

## How was this patch tested?
Manually by running the example in the ticket with and without a principal. Specifically I tested it on a dc/os 1.10 cluster with 7 nodes and played with reservations. From the master node in order to reserve resources I executed:
```for i in 0 1 2 3 4 5 6
do
curl -i \
-d slaveId=90ec65ea-1f7b-479f-a824-35d2527d6d26-S$i \
-d resources='[
{
"name": "cpus",
"type": "SCALAR",
"scalar": { "value": 2 },
"role": "spark-role",
"reservation": {
"principal": ""
}
},
{
"name": "mem",
"type": "SCALAR",
"scalar": { "value": 8026 },
"role": "spark-role",
"reservation": {
"principal": ""
}
}
]' \
-X POST http://master.mesos:5050/master/reserve
done
```
Nodes had 4 cpus (m3.xlarge instances) and I reserved either 2 or 4 cpus (all for a role).
I verified it launches tasks on nodes with reserved resources under `spark-role` role only if
a) there are remaining resources for (*) default role and the spark driver has no role assigned to it.
b) the spark driver has a role assigned to it and it is the same role used in reservations.
I also tested this locally on my machine.

Adding spark image reader, an implementation of schema for representing images in spark DataFrames
The code is taken from the spark package located here:

# Background and motivation
As Apache Spark is being used more and more in the industry, some new use cases are emerging for different data formats beyond the traditional SQL types or the numerical types (vectors and matrices). Deep Learning applications commonly deal with image processing. A number of projects add some Deep Learning capabilities to Spark (see list below), but they struggle to communicate with each other or with MLlib pipelines because there is no standard way to represent an image in Spark DataFrames. We propose to federate efforts for representing images in Spark by defining a representation that caters to the most common needs of users and library developers.
This SPIP proposes a specification to represent images in Spark DataFrames and Datasets (based on existing industrial standards), and an interface for loading sources of images. It is not meant to be a full-fledged image processing library, but rather the core description that other libraries and users can rely on. Several packages already offer various processing facilities for transforming images or doing more complex operations, and each has various design tradeoffs that make them better as standalone solutions.
This project is a joint collaboration between Microsoft and Databricks, which have been testing this design in two open source packages: MMLSpark and Deep Learning Pipelines.
The proposed image format is an in-memory, decompressed representation that targets low-level applications. It is significantly more liberal in memory usage than compressed image representations such as JPEG, PNG, etc., but it allows easy communication with popular image processing libraries and has no decoding overhead.

## What changes were proposed in this pull request?
This PR proposes to fix `dev/run-tests.py` script to support Python 3.
Here are some backgrounds. Up to my knowledge,
In Python 2,
- `unicode` is NOT `str` in Python 2 (`type("foo") != type(u"foo")`).
- `str` has an alias, `bytes` in Python 2 (`type("foo") == type(b"foo")`).
In Python 3,
- `unicode` was (roughly) replaced by `str` in Python 3 (`type("foo") == type(u"foo")`).
- `str` is NOT `bytes` in Python 3 (`type("foo") != type(b"foo")`).
So, this PR fixes:
1. Use `b''` instead of `''` so that both `str` in Python 2 and `bytes` in Python 3 can be hanlded. `sbt_proc.stdout.readline()` returns `str` (which has an alias, `bytes`) in Python 2 and `bytes` in Python 3
2. Similarily, use `b''` instead of `''` so that both `str` in Python 2 and `bytes` in Python 3 can be hanlded. `re.compile` with `str` pattern does not seem supporting to match `bytes` in Python 3:
Actually, this change is recommended up to my knowledge - https://docs.python.org/3/howto/pyporting.html#text-versus-binary-data:
> Mark all binary literals with a b prefix, textual literals with a u prefix
## How was this patch tested?
I manually tested this via Python 3 with few additional changes to reduce the elapsed time.

## What changes were proposed in this pull request?
Using zstd compression for Spark jobs spilling 100s of TBs of data, we could reduce the amount of data written to disk by as much as 50%. This translates to significant latency gain because of reduced disk io operations. There is a degradation CPU time by 2 - 5% because of zstd compression overhead, but for jobs which are bottlenecked by disk IO, this hit can be taken.
## Benchmark
Please note that this benchmark is using real world compute heavy production workload spilling TBs of data to disk
| | zstd performance as compred to LZ4 |
| ------------- | -----:|
| spill/shuffle bytes | -48% |
| cpu time | + 3% |
| cpu reservation time | -40%|
| latency | -40% |
## How was this patch tested?
Tested by running few jobs spilling large amount of data on the cluster and amount of intermediate data written to disk reduced by as much as 50%.

I first tested and checked lintr-1.0.1 but it looks many important fixes are missing (for example, checking 100 length). So, I instead tried the latest commit, 5431140ffe, in my local and fixed the check failures.
It looks it has fixed many bugs and now finds many instances that I have observed and thought should be caught time to time, here I filed [the results](https://gist.github.com/HyukjinKwon/4f59ddcc7b6487a02da81800baca533c).

This PR doesn't expose these metrics to any sink, to leverage this feature, still requires to connect to either MetricsSystem or collect them back to Driver to display.

There was a bug in Univocity Parser that causes the issue in SPARK-20978. This was fixed as below:
```scala
val df = spark.read.schema("a string, b string, unparsed string").option("columnNameOfCorruptRecord", "unparsed").csv(Seq("a").toDS())
df.show()
```
**Before**
```
java.lang.NullPointerException

```

It was fixed in 2.5.0 and 2.5.4 was released. I guess it'd be safe to upgrade this.
## How was this patch tested?
Unit test added in `CSVSuite.scala`.

…build; fix some things that will be warnings or errors in 2.12; restore Scala 2.12 profile infrastructure
## What changes were proposed in this pull request?
This change adds back the infrastructure for a Scala 2.12 build, but does not enable it in the release or Python test scripts.
In order to make that meaningful, it also resolves compile errors that the code hits in 2.12 only, in a way that still works with 2.11.
It also updates dependencies to the earliest minor release of dependencies whose current version does not yet support Scala 2.12. This is in a sense covered by other JIRAs under the main umbrella, but implemented here. The versions below still work with 2.11, and are the _latest_ maintenance release in the _earliest_ viable minor release.
- Scalatest 2.x -> 3.0.3
- Chill 0.8.0 -> 0.8.4
- Clapper 1.0.x -> 1.1.2
- json4s 3.2.x -> 3.4.2
- Jackson 2.6.x -> 2.7.9 (required by json4s)
This change does _not_ fully enable a Scala 2.12 build:
- It will also require dropping support for Kafka before 0.10. Easy enough, just didn't do it yet here
- It will require recreating `SparkILoop` and `Main` for REPL 2.12, which is SPARK-14650. Possible to do here too.
What it does do is make changes that resolve much of the remaining gap without affecting the current 2.11 build.
## How was this patch tested?
Existing tests and build. Manually tested with `./dev/change-scala-version.sh 2.12` to verify it compiles, modulo the exceptions above.

Mesos has secrets primitives for environment and file-based secrets, this PR adds that functionality to the Spark dispatcher and the appropriate configuration flags.
Unit tested and manually tested against a DC/OS cluster with Mesos 1.4.

This PR bumps the ANTLR version to 4.7, and fixes a number of small parser related issues uncovered by the bump.
The main reason for upgrading is that in some cases the current version of ANTLR (4.5) can exhibit exponential slowdowns if it needs to parse boolean predicates. For example the following query will take forever to parse:
```sql
SELECT *
FROM RANGE(1000)
WHERE
TRUE
AND NOT upper(DESCRIPTION) LIKE '%FOO%'
AND NOT upper(DESCRIPTION) LIKE '%FOO%'
AND NOT upper(DESCRIPTION) LIKE '%FOO%'
AND NOT upper(DESCRIPTION) LIKE '%FOO%'
AND NOT upper(DESCRIPTION) LIKE '%FOO%'
AND NOT upper(DESCRIPTION) LIKE '%FOO%'
AND NOT upper(DESCRIPTION) LIKE '%FOO%'
AND NOT upper(DESCRIPTION) LIKE '%FOO%'
AND NOT upper(DESCRIPTION) LIKE '%FOO%'
AND NOT upper(DESCRIPTION) LIKE '%FOO%'
AND NOT upper(DESCRIPTION) LIKE '%FOO%'
AND NOT upper(DESCRIPTION) LIKE '%FOO%'
AND NOT upper(DESCRIPTION) LIKE '%FOO%'
AND NOT upper(DESCRIPTION) LIKE '%FOO%'
AND NOT upper(DESCRIPTION) LIKE '%FOO%'
AND NOT upper(DESCRIPTION) LIKE '%FOO%'
AND NOT upper(DESCRIPTION) LIKE '%FOO%'
AND NOT upper(DESCRIPTION) LIKE '%FOO%'
```
This is caused by a know bug in ANTLR (https://github.com/antlr/antlr4/issues/994), which was fixed in version 4.6.

Like Parquet, this PR aims to depend on the latest Apache ORC 1.4 for Apache Spark 2.3. There are key benefits for Apache ORC 1.4.
- Stability: Apache ORC 1.4.0 has many fixes and we can depend on ORC community more.
- Maintainability: Reduce the Hive dependency and can remove old legacy code later.
Later, we can get the following two key benefits by adding new ORCFileFormat in SPARK-20728 (#17980), too.
- Usability: User can use ORC data sources without hive module, i.e, -Phive.
- Speed: Use both Spark ColumnarBatch and ORC RowBatch together. This will be faster than the current implementation in Spark.

This is trivial, but bugged me. We should download software over HTTPS.
And we can use RAT 0.12 while at it to pick up bug fixes.

This pr updated `lz4-java` to the latest (v1.4.0) and removed custom `LZ4BlockInputStream`. We currently use custom `LZ4BlockInputStream` to read concatenated byte stream in shuffle. But, this functionality has been implemented in the latest lz4-java (https://github.com/lz4/lz4-java/pull/105). So, we might update the latest to remove the custom `LZ4BlockInputStream`.
Major diffs between the latest release and v1.3.0 in the master are as follows (62f7547abb...6d4693f562);
- fixed NPE in XXHashFactory similarly
- Don't place resources in default package to support shading
- Fixes ByteBuffer methods failing to apply arrayOffset() for array-backed
- Try to load lz4-java from java.library.path, then fallback to bundled
- Add ppc64le binary
- Add s390x JNI binding
- Add basic LZ4 Frame v1.5.0 support
- enable aarch64 support for lz4-java
- Allow unsafeInstance() for ppc64le archiecture
- Add unsafeInstance support for AArch64
- Support 64-bit JNI build on Solaris
- Avoid over-allocating a buffer
- Allow EndMark to be incompressible for LZ4FrameInputStream.
- Concat byte stream
