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.
