    Description

      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.
