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. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
