[jira] [Resolved] (HBASE-10293) Master and RS GC logs can conflict
when run on same host
[ https://issues.apache.org/jira/browse/HBASE-10293?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Nick Dimiduk resolved HBASE-10293.
----------------------------------
Resolution: Not A Problem
This is actually an Ambari issue. I've opened AMBARI-4255.
Sorry for the noise.

> Key: HBASE-10293
> URL: https://issues.apache.org/jira/browse/HBASE-10293
> Project: HBase
> Issue Type: Bug
> Components: scripts
> Affects Versions: 0.96.1.1
> Reporter: Nick Dimiduk

> My issue manifests when I uncomment the line {{export SERVER_GC_OPTS=...}} in hbase-env.sh and start HBase. It's a single node in distributed mode, so both a Master and RegionServer are started on that host. Both start commands are run in the same minute, so only one gc.log-`date` file is created. `lsof` indicates two processes are writing to that file and the output of `ps` confirms they both received the same {{-Xloggc:/grid/0/var/log/hbase/gc.log-201401071515}} argument.
> Presumably, the same will happen for folks running the thrift and rest gateways on the same box (any java process itemized in the server_cmds array in bin/hbase).
> Related (the reason I discovered this issue in the first place), stopping the master process results in its gc.log being truncated.
