Re: [External] Re: Accumulo 1.10 - Failed to obtain Problem reports

Yes, it happened when accumulo was starting up but it persisted after the master was up.
I restarted the monitor, per your comment, and the error is resolved.

Was Accumulo still starting up?  I think these errors are common if the Monitor starts up before the Master is ready.

I noticed that the accumulo monitor page did not display any INFO or Warning messages.
I checked the logs for the monitor and found the following:

Did anyone run into this issue and what's the solution. My google search found references to a 2012 post but no solution.
