Subject [jira] Created: (HADOOP-2527) Poor distribution of regions
Date Fri, 04 Jan 2008 19:31:33 GMT
Poor distribution of regions
----------------------------

                 Key: HADOOP-2527
                 URL: https://issues.apache.org/jira/browse/HADOOP-2527
             Project: Hadoop
          Issue Type: Improvement
          Components: contrib/hbase
    Affects Versions: 0.15.0
         Environment: CentOS 5
            Reporter: Chris Kline
            Priority: Minor


We get poor distribution of regions when we start up HBase.  We have a total of 13 nodes and
898 regions, which should yield an average of 69 regions per node.  Instead, one node has
173 regions and one node has 16 regions.
