host monitor is running and the cluster is green, no issues.
saw other posts relating to this warn message, but in our case the system was created recently and basically doing nothing. runs impala and shared filesystem. so far do not observe any failures of either of these features.
please advise on how to repair this issue and determine what failures this might be causing.
the event log full of chatter/noise, and this is one of the issues reported over and over.
