Subject HBase regionserver SIGSEGV periodically
Date Fri, 10 Jun 2016 16:35:55 GMT
Our regionservers are periodically seg faulting, roughly once a day, and I
would appreciate some help debugging. Some version details:

Java HotSpot(TM) 64-Bit Server VM (24.80-b11) for linux-amd64 JRE
(1.7.0_80-b15), built on Apr 10 2015 19:53:14 by "java_re" with gcc 4.3.0
20080428 (Red Hat 4.3.0-8)

hbase-regionserver 0.98.6+cdh5.3.2+83-1.cdh5.3.2.p0.17~precise-cdh5.3.2

The segfault log output is:
https://gist.github.com/hazzadous/aa5013f50824658e75b75fd860c73f02

This has details of the java options as well.  Heap is ~46GB using G1GC.

The log output from HBase around this event is:
https://gist.github.com/hazzadous/4b94b5dcb351a360881c04fb54b5a70f

I'm going to attempt to update to java 8 to see if there's any improvements
but any analysis will be appreciated.

Harry
