    Description

      We observer that Storm_Nimbus, storm_supervisor and NMStormTopology is consuming 100% CPU with all CPU cores. 

      We found that Dispatcher Thread is taking quiet lot CPU. We observer that this issue was also reported earlier in Jira with title "Short disruptor queue wait time leads to high CPU usage when idle

      https://issues.apache.org/jira/browse/STORM-503

      This say the issue got fixed in the version 0.9.6 while in the version 1.0.0 seems the issue is still fixed.

      Kindly help us to resolve this issue, or advice us with the stable version of Storm which has this issue resolved.
