      Description

      Per IMPALA-3006, the BIT_PACKED decoding in the parquet scanner is deprecated and the implementation is actually incorrect. We should add a warning with the intent of removing the support in a later release.

      Note that because of IMPALA-5636 Impala-generated Parquet files may claim to use BIT_PACKED encoding when they don't, so we should really only issue the warning if the encoding is used in a data page.
