Nicolas Spiegelberg commented on HBASE-4769:
--------------------------------------------
It looks like the other locations just call Runtime.getRuntime().halt(1)
directly. Maybe we should do the same? BTW : Patch originally done by Liyin &
reviewed by Kannan, so I'm not 100% sure what their reasoning was.
> Abort RegionServer Immediately on OOME

> 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.
