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 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.
