      Description

      The value of spark.memory.fraction is changed to 0.6 from 0.75, but the remain percent in document is unchanged.

      spark.memory.fraction expresses the size of M as a fraction of the (JVM heap space - 300MB) (default 0.6). The rest of the space `(25%)` is reserved for user data structures, internal metadata in Spark, and safeguarding against OOM errors in the case of sparse and unusually large records.
