             Summary: ESP co-location needs to consider some nodes may host too many ESP processes due to data in-balance
                 Key: TRAFODION-1500
                 URL: https://issues.apache.org/jira/browse/TRAFODION-1500
             Project: Apache Trafodion
          Issue Type: Bug
          Components: sql-cmp
            Reporter: Qifan Chen


When a table is range-partitioned, or stats partitioned, it is possible that the amount of the data hosted at each region server may not be uniform.  Assume region server s running on node n hosts more data than the rest of the region servers. With the current ESP co-location assignment,  node s will be assigned with more # of ESPs.
