    Description

      0: jdbc:drill:schema=dfs> select count(*) from cast_tbl_1 a, cast_tbl_2 b where a.c_timestamp = b.c_date;
      Query failed: RemoteRpcException: Failure while running fragment., Failure finding function that runtime code generation expected.  Signature: compare_to_nulls_high( DATE:OPTIONAL, TIMESTAMP:OPTIONAL ) returns INT:REQUIRED [ e17b546e-81ec-49f0-ac91-f5714f570971 on atsqa4-134.qa.lab:31010 ]
