ramkrishna.s.vasudevan commented on HBASE-4769: ----------------------------------------------- I think adding this config to the JVM args will give you a heap dump -XX:+HeapDumpOnOutOfMemoryError. > Abort RegionServer Immediately on OOME > -------------------------------------- > > Key: HBASE-4769 > URL: https://issues.apache.org/jira/browse/HBASE-4769 > Project: HBase > Issue Type: Bug > Affects Versions: 0.94.0 > Reporter: Nicolas Spiegelberg > Assignee: Nicolas Spiegelberg > Fix For: 0.92.0, 0.94.0 > > Attachments: HBASE-4769.patch, HBASE-4769.patch > > > Currently, when the HRegionServer runs out of the memory, it will call > master, which will cause more heap allocations and throw a second exception > that it's run out of memory again. The easiest & safest way to avoid this > OOME storm is to abort the RegionServer immediately when it hits the memory > boundary.
