> Turn worker GC logging on by default

> This would be an update to the default worker.childopts. The logs should be
> configured to have a ceiling on the amount of space they use.

> hausdorff:
> What sounds like a reasonable amount of default space for logging to you?
> -----------------------------------------------------------------------------------------------------
> mrflip:
> This is what we've been using; it will use no more than 10 files of 1MB each.
> Most gc logging statements are on except PrintGCApplicationStoppedTime.
> worker.childopts: >-
> -Xloggc:/var/log/storm/gc-worker-%ID%.log -verbose:gc

> The challenge here is -Xloggc:/var/log/storm/gc-worker-%ID%.log -- how would
> you like the directory to be specified? I can add a new config variable, or
> add a new % interpolant, or default it to /tmp/gc-worker-%ID%.log.
