Subject [jira] [Commented] (ACCUMULO-892) shutdown doesn't use all minor compaction threads
Date Thu, 24 Jan 2013 14:51:15 GMT


Keith Turner commented on ACCUMULO-892:

If tablet unloads were to use the normal compaction queue, may want to prioritize unload related
compactions on the queue.

> I have a test cluster which is loaded with a very large number of disks per node.  I
increased the number of minor compaction threads accordingly.  When I shut down accumulo,
I saw it minor compacting just one tablet at a time.  In another shell, I forced a flush,
and the data was pushed out much more quickly.  It would be nice if the minor compaction threads
could be used to make shutdown run more quickly.
