Subject [jira] [Commented] (HBASE-6878) DistributerLogSplit can fail to resubmit a task done if there is an exception during the log archiving
Date Wed, 26 Sep 2012 10:18:07 GMT

    [ https://issues.apache.org/jira/browse/HBASE-6878?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13463686#comment-13463686
] 

nkeywal commented on HBASE-6878:
--------------------------------

Any feedback on this? It's in the "probability of occurrence: very low" category, but HBASE-6738
increases the delay so the probability, so I would prefer to commit the two altogether.

A few lines after the one mentioned in the description there is a similar pattern. I will
fix both of them if it's confirmed.

> Without it, the task won't be resubmitted if the delay is not reached, and the task will
be marked as failed.
