----------------------------------------
bq. *shrug* I don't feel strongly about the issue
Same here. :-)
> Master and RS GC logs can conflict when run on same host

> 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.
