Summary: Vectorization: Fix more NULL / Wrong Results issues and
avoid unnecessary casts/conversions
Key: HIVE-20315
URL: https://issues.apache.org/jira/browse/HIVE-20315
Project: Hive
Issue Type: Bug
Components: Hive
Reporter: Matt McCline
Assignee: Matt McCline
Generate multi-byte Unicode characters in addition to regular single byte
characters for random data.
Don't CAST from STRING/VARCHAR/CHAR TO STRING since all are stored in
vectorization without padding.
Fix vectorized BETWEEN expression work to avoid unnecessary CAST of DECIMAL
constants.
Fix NULL / Wrong Results issues in VectorElt.
Change performance Q files to generate non-user EXPLAIN with VECTORIZATION
display so unnecesary CAST / DECIMAL_64 conversions are visible.
