[SPARK-4116][YARN]Delete the abandoned log4j-spark-container.properties

Since its name reduced at https://github.com/apache/spark/pull/560, the log4j-spark-container.properties was never used again.
And I have searched its name globally in code and found no cite.

[SPARK-4110] Wrong comments about default settings in spark-daemon.sh

In spark-daemon.sh, thare are following comments.

    #   SPARK_CONF_DIR  Alternate conf dir. Default is ${SPARK_PREFIX}/conf.
    #   SPARK_LOG_DIR   Where log files are stored.  PWD by default.

But, I think the default value for SPARK_CONF_DIR is `${SPARK_HOME}/conf` and for SPARK_LOG_DIR is `${SPARK_HOME}/logs`.

[SPARK-3657] yarn alpha YarnRMClientImpl throws NPE appMasterRequest.setTrackingUrl starting spark-shell

tgravescs reported this issue.

Following is quoted from tgravescs' report.

YarnRMClientImpl.registerApplicationMaster can throw null pointer exception when setting the trackingurl if its empty:

    appMasterRequest.setTrackingUrl(new URI(uiAddress).getAuthority())

I hit this just start spark-shell without the tracking url set.

[SPARK-4065] Add check for IPython on Windows

This issue employs logic similar to the bash launcher (pyspark) to check
if IPTYHON=1, and if so launch ipython with options in IPYTHON_OPTS.
This fix assumes that ipython is available in the system Path, and can
be invoked with a plain "ipython" command.

[Spark 3922] Refactor spark-core to use Utils.UTF_8

A global UTF8 constant is very helpful to handle encoding problems when converting between String and bytes. There are several solutions here:

1. Add `val UTF_8 = Charset.forName("UTF-8")` to Utils.scala
2. java.nio.charset.StandardCharsets.UTF_8 (require JDK7)
3. io.netty.util.CharsetUtil.UTF_8
4. com.google.common.base.Charsets.UTF_8
5. org.apache.commons.lang.CharEncoding.UTF_8
6. org.apache.commons.lang3.CharEncoding.UTF_8

IMO, I prefer option 1) because people can find it easily.

This is a PR for option 1) and only fixes Spark Core.

[SPARK-3343] [SQL] Add serde support for CTAS

Currently, `CTAS` (Create Table As Select) doesn't support specifying the `SerDe` in HQL. This PR will pass down the `ASTNode` into the physical operator `execution.CreateTableAsSelect`, which will extract the `CreateTableDesc` object via Hive `SemanticAnalyzer`. In the meantime, I also update the `HiveMetastoreCatalog.createTable` to optionally support the `CreateTableDesc` for table creation.

[SPARK-4084] Reuse sort key in Sorter

Sorter uses generic-typed key for sorting. When data is large, it creates lots of key objects, which is not efficient. We should reuse the key in Sorter for memory efficiency. This change is part of the petabyte sort implementation from rxin .

The `Sorter` class was written in Java and marked package private. So it is only available to `org.apache.spark.util.collection`. I renamed it to `TimSort` and add a simple wrapper of it, still called `Sorter`, in Scala, which is `private[spark]`.

The benchmark code is updated, which now resets the array before each run. Here is the result on sorting primitive Int arrays of size 25 million using Sorter:

~~~

So with key reuse, it is faster and less likely to trigger GC.

[SPARK-4008] Fix "kryo with fold" in KryoSerializerSuite

`zeroValue` will be serialized by `spark.closure.serializer` but `spark.closure.serializer` only supports the default Java serializer. So it must not be `ClassWithoutNoArgConstructor`, which can not be serialized by the Java serializer.

This PR changed `zeroValue` to null and updated the test to make it work correctly.
