    • Type: Bug

    • Resolution: Fixed
    • Affects Version/s: None

      Description

      To reproduce:
      set compression_codec=gzip;
      >COMPRESSION_CODEC set to gzip
      compute stats functional.alltypes;
      >Query: compute stats functional.alltypes
      >ERROR: Invalid compression codec: 2

      This kind of issue is typical with query options and compute stats - compute stats converts enums to their number representation, which is handled by most query options, see https://github.com/apache/impala/blob/adced30896ade0f71e64cc2d5bad1cd9f43119b7/be/src/service/query-options.cc#L532 for an example.
