milleruntime opened a new issue #196:
URL: https://github.com/apache/accumulo-testing/issues/196
I was running 4 threads for the MultiTable randomwalk test locally on my
machine using Uno. I had 2 tservers running. After some time, one of the
threads died while trying to do copyTable. Typically, I see this error when I
kill the test myself. But this time the tserver reported the error on its own.

I am not sure what happened but the Hadoop MR job is still running.
