Tim Armstrong created IMPALA-6076:
-------------------------------------
Summary: Add deprecation warning for BIT_PACKED encoding.
Key: IMPALA-6076
URL: https://issues.apache.org/jira/browse/IMPALA-6076
Project: IMPALA
Issue Type: Improvement
Components: Backend
Affects Versions: Impala 2.10.0
Reporter: Tim Armstrong
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.
