Change subject: cdh:hive: set minimum jvm heap size to 4g ...................................................................... cdh:hive: set minimum jvm heap size to 4g After fixing the Xmx settings and adding monitoring to GC metrics there seems to be frequent collections for the young generation even if not really needed. We observed this behavior on other Hadoop daemons, and raising the Xms settings helped a lot.
