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
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. Part
of the 89-fb to trunk port.
