Hi Fang, @hustfxj. Great question! We also met the same problem. Actually
our setting for gc log name is "-Xloggc:artifacts/gc.%p.log". Then gc log won't
be overwritten due to worker restating.
Then we will also need to https://issues.apache.org/jira/browse/STORM-1206
to avoid too many gc files' names crashing the logviewer JVM (this might happen
in a very very extreme and rare case, only once in our cluster).
