[SPARK-1395] Allow "local:" URIs to work on Yarn.

This only works for the three paths defined in the environment
(SPARK_JAR, SPARK_YARN_APP_JAR and SPARK_LOG4J_CONF).

Tested by running SparkPi with local: and file: URIs against Yarn cluster (no "upload" shows up in logs in the local case).

SPARK-1408 Modify Spark on Yarn to point to the history server when app ...

...finishes

Note this is dependent on https://github.com/apache/spark/pull/204 to have a working history server, but there are no code dependencies.

This also fixes SPARK-1288 yarn stable finishApplicationMaster incomplete. Since I was in there I made the diagnostic message be passed properly.

SPARK-1483: Rename minSplits to minPartitions in public APIs

https://issues.apache.org/jira/browse/SPARK-1483

From the original JIRA: " The parameter name is part of the public API in Scala and Python, since you can pass named parameters to a method, so we should name it to this more descriptive term. Everywhere else we refer to "splits" as partitions." - @mateiz

[SPARK-1520] remove fastutil from dependencies

A quick fix for https://issues.apache.org/jira/browse/SPARK-1520

By excluding fastutil, we bring the number of files in the assembly jar back under 65536, so Java 7 won't create the assembly jar in zip64 format, which cannot be read by Java 6.

With this change, the assembly jar now has about 60000 entries (58000 files), tested with both sbt and maven.

SPARK-1523: improve the readability of code in AkkaUtil

Actually it is separated from https://github.com/apache/spark/pull/85 as suggested by @rxin

compare

https://github.com/apache/spark/blob/master/core/src/main/scala/org/apache/spark/util/AkkaUtils.scala#L122

and

https://github.com/apache/spark/blob/master/core/src/main/scala/org/apache/spark/util/AkkaUtils.scala#L117

the first one use get and then toLong, the second one getLong....better to make them consistent

very very small fix........

SPARK-1456 Remove view bounds on Ordered in favor of a context bound on Ordering.

This doesn't require creating new Ordering objects per row.  Additionally, [view bounds are going to be deprecated](https://issues.scala-lang.org/browse/SI-7629), so we should get rid of them while APIs are still flexible.
