Subject [jira] [Created] (ACCUMULO-770) TableLoadBalancer / DefaultLoadBalancer assigns tables unevenly
Date Thu, 20 Sep 2012 18:04:07 GMT
Eric Newton created ACCUMULO-770:
------------------------------------

             Summary: TableLoadBalancer / DefaultLoadBalancer assigns tables unevenly
                 Key: ACCUMULO-770
                 URL: https://issues.apache.org/jira/browse/ACCUMULO-770
             Project: Accumulo
          Issue Type: Bug
          Components: master
    Affects Versions: 1.4.1
            Reporter: Eric Newton
            Assignee: Eric Newton
             Fix For: 1.4.2


During assignment, each table balancer starts assigning tablets in order.  This ensures the
the "lowest" tabletserver gets at least one tablet for each table.  This can make for an unbalanced
cluster when there are many small tables.  Randomize the list of tablets in the DefaultLoadBalancer
to evenly distribute tablets on a new cluster.
