Subject [jira] [Commented] (ACCUMULO-2998) provide a mechanism to allow clients to wait for balance
Date Thu, 17 Jul 2014 14:15:07 GMT

    [ https://issues.apache.org/jira/browse/ACCUMULO-2998?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14064951#comment-14064951

Keith Turner commented on ACCUMULO-2998:
----------------------------------------

[~ecn] and I had an offline discussion about this issue.  A few points that I think are interesting

 * The little test utility I wrote waits for tablets to be evenly spread, but this makes assumptions
about how the pluggable balancer behaves.  [~ecn]'s changes are more general and wait until
the pluggable balance has no more work to do.   
 * The method waits for the entire system to be balanced.  I was thinking it may be more useful
to wait for a particular table to be balanced.  However, the use does not have to use the
per table balancer making it tricky to implement waiting for a particular table to balance.

> It would be nice to wait for the balancer to run and find no work to do after creating
a bunch of splits.
