Matei Zaharia resolved SPARK-2014.
----------------------------------
Resolution: Fixed
Fix Version/s: 1.1.0
> Make PySpark store RDDs in MEMORY_ONLY_SER with compression by default
> ----------------------------------------------------------------------
>
> Key: SPARK-2014
> URL: https://issues.apache.org/jira/browse/SPARK-2014
> Project: Spark
> Issue Type: Improvement
> Components: PySpark
> Reporter: Matei Zaharia
> Assignee: Prashant Sharma
> Fix For: 1.1.0
>
>
> Since the data is serialized on the Python side, there's not much point in
> keeping it as byte arrays in Java, or even in skipping compression. We should
> make cache() in PySpark use MEMORY_ONLY_SER and turn on spark.rdd.compress
> for it.
