Subject [jira] [Commented] (ACCUMULO-576) Extend TABLE_FAILURES_IGNORE to major compactions
Date Fri, 04 May 2012 19:46:47 GMT

    [ https://issues.apache.org/jira/browse/ACCUMULO-576?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13268662#comment-13268662
] 

Keith Turner commented on ACCUMULO-576:
---------------------------------------

One strategy could be to attempt the compaction, when a read failure occurs remove the offending
file and restart the compaction.  When the compaction finishes only remove the files that
were successfully compacted.

> We currently have TABLE_FAILURES_IGNORE which will silently ignore failures/hangs while
scanning. We should look into extending this option for major compactions. The tricky part
of this is that we don't want the files that we unread to be deleted, just ignored in the
major compaction. This may not be feasible, but it's something worth looking into.
