[jira] [Commented] (ACCUMULO-202) master does not rebalance after a node fails

    [ https://issues.apache.org/jira/browse/ACCUMULO-202?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13178188#comment-13178188 ] 

Eric Newton commented on ACCUMULO-202:
--------------------------------------

The bug is definitely in 1.3.5. If you take down an arbitrary node, and the monitor displays a notice that the node is unresponsive for more than 30 seconds, you are seeing this bug. To recover, restart the master.  [r1212020|http://svn.apache.org/viewvc?view=rev&rev=1212020] should fix 1.3.5.

> The master seems to be trying to contact a dead tablet server.  The master will not re-balance if the metrics it has for a tablet server are out-of-date.  Tablets seem to be assigned properly; just not balanced.
