Description
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.
