Subject [jira] [Commented] (ACCUMULO-1345) Provide feedback that a compaction is "stuck"
Date Fri, 21 Jun 2013 17:54:20 GMT

    [ https://issues.apache.org/jira/browse/ACCUMULO-1345?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13690517#comment-13690517

Mike Drob commented on ACCUMULO-1345:
-------------------------------------

Thinking about this some more, I'm not sure that {{listcompactions}} filtering on tables would
be good enough. Compactions should report to the master that they have made progress (similar
to MR tasks), either through entries read/written, or through an explicit progress call inside
of an iterator. If progress hasn't been made for a configurable amount of time (10 minutes)
then action should be taken.

> The system should be able to detect when a compaction has not read or written data in
a while, indicating that it may be stuck on something (e.g. an infinite loop in a user iterator).
