--------------------------------------
Here are gc logs related JVM parameters that we use for Hadoop daemons:
{noformat}
-Xloggc:/home/gs/var/log/$USER/gc.log-`date +'%Y%m%d%H%M'` -verbose:gc
-XX:+PrintGCDetails -XX:+PrintGCTimeStamps -XX:+PrintGCDateStamps
{noformat}
> Roll gc logs in run-class.sh

> Key: SAMZA-20
> URL: https://issues.apache.org/jira/browse/SAMZA-20
> Project: Samza
> Issue Type: Bug
> Reporter: Chris Riccomini
>
> The run-class.sh script defaults to setting up a gc.log file, if SAMZA_OPTS
> is undefined.
> Newer versions of Java 6, and Java 7 allow you to roll gc log files with
> -XX:+UseGCLogFileRotation. See
> http://stackoverflow.com/questions/3822097/rolling-garbage-collector-logs-in-java
> for details.
> Should also validate that the change doesn't break with older Java 6 versions.
> Also, [~sureshms] was saying that there's an alternate way to do this. Suresh
> - care to chime in?
