> After deploying 1.3.4 stack following alerts appears:
> {code}
> HistoryServer RPC latency
> CRIT for 25 minutes
> CRITICAL: Data inaccessible, Status code = 0
> HistoryServer process
> CRIT for 28 minutes
> Connection refused
> HistoryServer Web UI
> WARN for 27 minutes
> WARNING: HistoryServer Web UI not accessible : http://c6402.ambari.apache.org:19888/jobhistory
> {code}
> Restarting HistoryServer and MapReduce didn't solve the problem. This problem is not reproducible every time, but for me it reproduces constantly.
> Please see screenshot and logs attached. BTW, all quick links on MapReduce page seems live. 
> And there is a quicklink "JobHistory Server" that points to: http://c6402.ambari.apache.org:51111/jobhistoryhome.jsp and its working.
> It's not very clear, is JobHistory Server and History Server the same thing, and why Nagios checks http://c6402.ambari.apache.org:19888/jobhistory.
