[jira] [Created] (IMPALA-5636) Impala writer claims that file uses BIT_PACKED encoding when it doesn't

Tim Armstrong created IMPALA-5636:
-------------------------------------

             Summary: Impala writer claims that file uses BIT_PACKED encoding when it doesn't
                 Key: IMPALA-5636
                 URL: https://issues.apache.org/jira/browse/IMPALA-5636
             Project: IMPALA
          Issue Type: Bug
          Components: Backend
            Reporter: Tim Armstrong
            Priority: Minor


The Parquet writer always adds the BIT_PACKED and RLE encodings even though (I'm pretty sure) we never use the (deprecated) BIT_PACKED encoding for rep/def levels.  One way of seeing this is using parquet-tool.

We should confirm that BIT_PACKED is never used and then stop writing it out.
