> Key: SPARK-5157
> URL: https://issues.apache.org/jira/browse/SPARK-5157
> Project: Spark
> Issue Type: Improvement
> Components: YARN
> Affects Versions: 1.3.0
> Reporter: Kousuke Saruta
> Assignee: Kousuke Saruta
> Priority: Trivial
> Fix For: 1.3.0, 1.4.0
>
>
> When we set `SPARK_USE_CONC_INCR_GC`, ConcurrentMarkSweepGC works on the AM.
> Actually, if ConcurrentMarkSweepGC is set for the JVM, following JVM options
> are set automatically and implicitly.
> * MaxTenuringThreshold=0
> * SurvivorRatio=1024
> Those can not be proper value for most cases.
