------------------------------------

             Summary: LP Bug: 1343566 - PARALLEL_NUM_ESPS should have an influence on a parallel hbase scan plan
                 Key: TRAFODION-459
                 URL: https://issues.apache.org/jira/browse/TRAFODION-459
             Project: Apache Trafodion
          Issue Type: Bug
          Components: sql-cmp
            Reporter: Qifan Chen
            Assignee: Qifan Chen
             Fix For: 0.7 (pre-incubation)


Currently, the CQD has no influence the # of esps assigned for parallel hbase scan, which is computed as the min of the total # of allowed ESPs, and CQD HBASE_MAX_ESPS. 

The workaround is to use the combination of CQDs

ARKCMP_FAKE_HW  ‘ON’;
DEF_NUM_NODES_IN_ACTIVE_CLUSTERS ‘16’;  -- for a 16-way parallel hbase scan.
