Subject Re: Zookeeper Session Timeout
Date Thu, 06 Jun 2013 12:51:46 GMT
I haven't seen this problem, however I have not run a smoke test on Blur in
a month or so.  I will try to run a test today.  However this sounds like a
GC problem, perhaps the heap size is not set high enough?

By adding -Xloggc to you jvm options you can see if their are long pauses
in GC which would cause the timeout.  You can look in the blur-env.sh for
an example of how to use it.

Also what is the number of tables and number of shards in each table.  How
much heap are you running?  How large are the rows you are running?

Thanks.

Aaron
