Subject [jira] [Commented] (ACCUMULO-2247) random walk fails when server gets EOFException
Date Wed, 11 Feb 2015 17:52:11 GMT

    [ https://issues.apache.org/jira/browse/ACCUMULO-2247?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14316630#comment-14316630
] 

Eric Newton commented on ACCUMULO-2247:
---------------------------------------

Large numbers of WAL's were created, too. Might want to add an exponential back-off and clear
error message about HDFS failure.
