[SPARK-1549] Add Python support to spark-submit
This PR updates spark-submit to allow submitting Python scripts (currently
only with deploy-mode=client, but that's all that was supported before) and
updates the PySpark code to properly find various paths, etc. One significant
change is that we assume we can always find the Python files either from the
Spark assembly JAR (which will happen with the Maven assembly build in
make-distribution.sh) or from SPARK_HOME (which will exist in local mode even
if you use sbt assembly, and should be enough for testing). This means we no
longer need a weird hack to modify the environment for YARN.
This patch also updates the Python worker manager to run python with -u,
which means unbuffered output (send it to our logs right away instead of
waiting a while after stuff was written); this should simplify debugging.
In addition, it fixes https://issues.apache.org/jira/browse/SPARK-1709,
setting the main class from a JAR's Main-Class attribute if not specified by
the user, and fixes a few help strings and style issues in spark-submit.
In the future we may want to make the `pyspark` shell use spark-submit as
well, but it seems unnecessary for 1.0.
