This code used to be throw exception in spark-shell, because while shuffling ```JavaSerializer```uses ```defaultClassLoader``` which was defined like ```env.serializer.setDefaultClassLoader(urlClassLoader)```.
It should be ```env.serializer.setDefaultClassLoader(replClassLoader)```, like
```
override def run() {
val deserializeStartTime = System.currentTimeMillis()
Thread.currentThread.setContextClassLoader(replClassLoader)
```
in TaskRunner.
When ```replClassLoader``` cannot be defined, it's identical with ```urlClassLoader```

Currently we would create a new streaming tab for each streamingContext even if there's already one on the same sparkContext which would cause duplicate StreamingTab created and none of them is taking effect.

val ssc = new StreamingContext(sc, Seconds(1))
val lines = ssc.socketTextStream("localhost", 9999, StorageLevel.MEMORY_AND_DISK_SER)
val words = lines.flatMap(_.split(" "))

This change encapsulates all the logic involved in launching a Spark job
into a small Java library that can be easily embedded into other applications.
The overall goal of this change is twofold, as described in the bug:
- Provide a public API for launching Spark processes. This is a common request
from users and currently there's no good answer for it.
- Remove a lot of the duplicated code and other coupling that exists in the
different parts of Spark that deal with launching processes.
A lot of the duplication was due to different code needed to build an
application's classpath (and the bootstrapper needed to run the driver in
certain situations), and also different code needed to parse spark-submit
command line options in different contexts. The change centralizes those
as much as possible so that all code paths can rely on the library for
handling those appropriately.

7795dd4 [Marcelo Vanzin] [core] [minor] Don't pollute source directory when running UtilsSuite.
This patch fixes two issues with the executor log viewing links added in Spark 1.3. In standalone mode, the log URLs might include a port value of 0 rather than the actual bound port of the UI, which broke the ability to view logs from workers whose web UIs had been configured to bind to ephemeral ports. In addition, the URLs used workers' local hostnames instead of respecting SPARK_PUBLIC_DNS, which prevented this feature from working properly on Spark EC2 clusters because the links would point to internal DNS names instead of external ones.
I included tests for both of these bugs:
- We now browse to the URLs and verify that they point to the expected pages.
- To test SPARK_PUBLIC_DNS, I changed the code that reads the environment variable to do so via `SparkConf.getenv`, then used a custom SparkConf subclass to mock the environment variable (this pattern is used elsewhere in Spark's tests).

Before we would get the following (benign) error if we called `sc.stop()` twice. This is because the listener bus would try to post the end event again even after it has already stopped. This happens occasionally when flaky tests fail, usually as a result of other sources of error. Either way we shouldn't be logging this error when it is not the cause of the failure.

The problem is that `ContextCleaner` may clean variables that belong to a different `SparkContext`. This can happen if the `SparkContext` to which the cleaner belongs stops, and a new one is started immediately afterwards in the same JVM. In this case, if the cleaner is in the middle of cleaning a broadcast, for instance, it will do so through `SparkEnv.get.blockManager`, which could be one that belongs to a different `SparkContext`.
JoshRosen and I suspect that this is the cause of many flaky tests, most notably the `JavaAPISuite`. We were able to reproduce the failure locally (though it is not deterministic and very hard to reproduce).

There are multiple issues with translating on set outlined in the JIRA.
This PR reverts the translation logic added to `SparkConf`. In the future, after the 1.3.0 release we will figure out a way to reorganize the internal structure more elegantly. For now, let's preserve the existing semantics of `SparkConf` since it's a public interface. Unfortunately this means duplicating some code for now, but this is all internal and we can always clean it up later.

Some users have reported difficulty in parsing the new event log format. Since we embed the metadata in the beginning of the file, when we compress the event log we need to skip the metadata because we need that information to parse the log later. This means we'll end up with a partially compressed file if event logging compression is turned on. The old format looks like:
```
sparkVersion = 1.3.0
compressionCodec = org.apache.spark.io.LZFCompressionCodec
=== LOG_HEADER_END ===
// actual events, could be compressed bytes
```
The new format in this patch puts the compression codec in the log file name instead. It also removes the metadata header altogether along with the Spark version, which was not needed. The new file name looks something like:
```
app_without_compression
app_123.lzf
app_456.snappy
```
I tested this with and without compression, using different compression codecs and event logging directories. I verified that both the `Master` and the `HistoryServer` can render both compressed and uncompressed logs as before.

When starting the history server, all the log files will be fetched and parsed in order to get the applications' meta data e.g. App Name, Start Time, Duration, etc. In our production cluster, there exist 2600 log files (160G) in HDFS and it costs 3 hours to restart the history server, which is a little bit too long for us.
It would be better, if the history server can show logs with missing information during start-up and fill the missing information after fetching and parsing a log file.

This fixes a non-deterministic bug introduced in #4021 that could cause tasks' accumulator updates to be lost. The problem is that `localAccums` should not hold weak references: after the task finishes running there won't be any strong references to these local accumulators, so they can get garbage-collected before the executor reads the `localAccums` map. We don't need weak references here anyways, since this map is cleared at the end of each task.

This is the safer parts of PR #4754:
- SPARK-5979: All dependencies with the groupId `org.apache.spark` passed through `--packages`, were being excluded from the dependency tree on the assumption that they would be in the assembly jar. This is not the case, therefore the exclusion rules had to be defined more explicitly.
- SPARK-6032: Ivy prints a whole lot of logs while retrieving dependencies. These were printed to `System.out`. Moved the logging to `System.err`.

Removing elements from a mutable HashSet while iterating over it can cause the
iteration to incorrectly skip over entries that were not removed. If this
happened, PythonRDD would write fewer broadcast variables than the Python
worker was expecting to read, which would cause the Python worker to hang
indefinitely.

Cache the value of the local root dirs to use for storing local data,
so that the same directories are reused.
Also, to avoid an extra level of nesting, use a different env variable
to propagate the local dirs from the Worker to the executors. And make
the executor directory use a different name.
