Tao Wang created SPARK-17010:
--------------------------------
Summary: [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
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.
