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).

NB on OS X the original `sed` command here will create files like `pom.xml-e` through the source tree though it otherwise works. It's like `-e` is also the arg to `-i`. I couldn't get rid of that even with `-i""`. No biggie.

Integration test suites in the JDBC data source (`MySQLIntegration` and `PostgresIntegration`) depend on docker-client 2.7.5, which transitively depends on Guava 17.0. Unfortunately, Guava 17.0 is causing test runtime binary compatibility issues when Spark is compiled against Hive 0.12.0, or Hadoop 2.4.
Considering `MySQLIntegration` and `PostgresIntegration` are ignored right now, I'd suggest moving them from the Spark project to the [Spark integration tests] [1] project. This PR removes both the JDBC data source integration tests and the docker-client test dependency.

Added an AMPLAB_JENKINS_BUILD_TOOL env. variable to allow differentiation between maven and sbt build / test suites. The only issue I found with this is that, when running maven builds I wasn't able to get individual package tests running without running a `mvn install` first. Not sure what Jenkins is doing wrt its env., but figured its much better to just test everything than install packages in the "~/.m2/" directory and only test individual items, esp. if this is predominantly for the Jenkins build.

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).

This PR contains the following changes:
1. Add a new method, `DataType.equalsIgnoreCompatibleNullability`, which is the middle ground between DataType's equality check and `DataType.equalsIgnoreNullability`. For two data types `from` and `to`, it does `equalsIgnoreNullability` as well as if the nullability of `from` is compatible with that of `to`. For example, the nullability of `ArrayType(IntegerType, containsNull = false)` is compatible with that of `ArrayType(IntegerType, containsNull = true)` (for an array without null values, we can always say it may contain null values). However, the nullability of `ArrayType(IntegerType, containsNull = true)` is incompatible with that of `ArrayType(IntegerType, containsNull = false)` (for an array that may have null values, we cannot say it does not have null values).
2. For the `resolved` field of `InsertIntoTable`, use `equalsIgnoreCompatibleNullability` to replace the equality check of the data types.
3. For our data source write path, when appending data, we always use the schema of existing table to write the data. This is important for parquet, since nullability direct impacts the way to encode/decode values. If we do not do this, we may see corrupted values when reading values from a set of parquet files generated with different nullability settings.
4. When generating a new parquet table, we always set nullable/containsNull/valueContainsNull to true. So, we will not face situations that we cannot append data because containsNull/valueContainsNull in an Array/Map column of the existing table has already been set to `false`. This change makes the whole data pipeline more robust.
5. Update the equality check of JSON relation. Since JSON does not really cares nullability, `equalsIgnoreNullability` seems a better choice to compare schemata from to JSON tables.

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.

Constructs like Hive `TRANSFORM` may generate malformed rows (via badly authored external scripts for example). I'm a bit hesitant to have this feature, since it introduces per-tuple cost when caching tables. However, considering caching tables is usually a one-time cost, this is probably worth having.

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.

The API signatire for join requires the JoinType to be the third parameter. The code examples provided for join show JoinType being provided as the 2nd parater resuling in errors (i.e. "df1.join(df2, "outer", $"df1Key" === $"df2Key") ). The correct sample code is df1.join(df2, $"df1Key" === $"df2Key", "outer")

e353340 [Paul Power] Updated comments use correct sample code for Dataframe joins
Currently LogisticRegressionWithLBFGS in python/pyspark/mllib/classification.py will invoke callMLlibFunc with a wrong "regType" parameter.
It was assigned to "str(regType)" which translate None(Python) to "None"(Java/Scala). The right way should be translate None(Python) to null(Java/Scala) just as what we did at LogisticRegressionWithSGD.

Examples illustrating difference between legacy mapReduceTriplets usage and aggregateMessages usage has type issues on the reduce for both operators.
Being just an example- changed example to reduce the message String by concatenation. Although non-optimal for performance.

db54173 [DEBORAH SIEGEL] fixed aggregateMessages example in graphX doc
When run ```select * from nzhang_part where hr = 'file,';```, it throws exception ```java.lang.IllegalArgumentException: Can not create a Path from an empty string```
. Because the path of hdfs contains comma, and FileInputFormat.setInputPaths will split path by comma.
