Subject Re: Master down?; tservers not listed in /tservers
Date Mon, 21 May 2012 19:32:05 GMT
The master in 1.3 has a small bug, in that it is not responsive to
monitoring if there are no tablet servers, so that's why it is showing down.

The LRU stats are printed in a background thread... ignore them.

Is your zookeeper setting in accumulo-site.xml still set to localhost?
