High CPU Utilization on Cluster while Idle

Question asked by mandoskippy on Jul 1, 2012
Latest reply on Jul 1, 2012 by mandoskippy
I have a mapr cluster that is currently hovering around 75 % CPU utilization cluster wide.  When I logon to  individual node, the cores are spiked by the hadoop/mapr java processes. I am perplexed, no jobs are running in job tracker. I do have rebalancing turned on, is that normal for a rebalance to take that much CPU?  Is there a way for me to trouble shoot what is actually happening here?  

Thanks!
