Hi Did you check your zookeeper? Check the zookeeper logs. May be some network fluctuation between your HBase cluster and Zookeeper. Also read the trouble shooting section of HBase w.r.t Zookeeper. May be the load on ZK is too heavy and there is some long Full GC happening. Regards Ram -O

Jorn, Did you restart mapreduce (the task trackers in particular) after the change? Hopefully when you restart you can check the TT's to make sure that /etc/zookeeper/* is not in its class path. Jon. On Thu, Dec 8, 2011 at 12:59 AM, Jorn Argelo - Ephorus < jorn.arg...@ephorus.com> wrote: > Hi
