      Description

      The query

      select count(ddate) from factsqlengineam_vec_orc where ddate like "2013%";

      Starts up but does not run in vectorization mode. Then during non-vectorized execution it crashes.

      Expected result:

      Query runs vectorized and runs successfully.

      Actual result:

      hive> select count(ddate) from factsqlengineam_vec_orc where ddate like "2013%";
      Total MapReduce jobs = 1

      Number of reduce tasks determined at compile time: 1
      In order to change the average load for a reducer (in bytes):
      set hive.exec.reducers.bytes.per.reducer=<number>
      In order to limit the maximum number of reducers:
      set hive.exec.reducers.max=<number>
      In order to set a constant number of reducers:
      set mapred.reduce.tasks=<number>
