-------------------------------
Summary: Controller message cleanup is spitting too many logs
Key: HELIX-689
URL: https://issues.apache.org/jira/browse/HELIX-689
Project: Apache Helix
Issue Type: Bug
Reporter: Hao Zhang
Currently we print out error log when we fail to remove logs. However, due to
ZK client limitation, we are printing logs even when the message is already
deleted, which should not be regarded as a failure
Need to perform log cleanup and only print out log when there is real error.
