Subject [jira] [Commented] (ACCUMULO-3092) BatchWriter does not notice when tserver fails, continues to send mutations to it
Date Mon, 29 Sep 2014 17:15:35 GMT

    [ https://issues.apache.org/jira/browse/ACCUMULO-3092?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14151913#comment-14151913
] 

Eric Newton commented on ACCUMULO-3092:
---------------------------------------

No, the client talks directly to zookeeper when reloading its cache. When discussing this
issue with [~dlmarion], he indicated that the tserver didn't die.  During my test, I saw the
client successfully send the mutation without killing the tserver.
