I tried running mvn verify -Psunny and the ReadWriteIT failed. Scans were
failing because of server side errors. Seeing lots exceptions like the
following in the tablet server logs. I suspect the RFile exception is caused
by reusing closed rfiles from the rfile pool. Not sure whats going on with the
memory iterator exception.
