Apache Spark reassigned SPARK-17010:
------------------------------------
Assignee: Apache Spark
> [MINOR]Wrong description in memory management document
> ------------------------------------------------------
>
> Key: SPARK-17010
> URL: https://issues.apache.org/jira/browse/SPARK-17010
> Project: Spark
> Issue Type: Bug
> Components: Documentation
> Affects Versions: 2.0.0
> Reporter: Tao Wang
> Assignee: Apache Spark
> Priority: Minor
>
> 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.
