    Description

      Follow-up on HIVE-13068.

      In test file ql/src/test/results/clientpositive/index_auto_unused.q.out.

      After HIVE-13068 goes in, the following filter is not folded after PartitionPruning is done:
      filterExpr: ((ds = '2008-04-09') and (12.0 = 12.0) and (UDFToDouble(key) < 10.0)) (type: boolean)

      Further, SimpleFetchOptimizer got disabled.

      All this needs further investigation.
