Sergey Shelukhin created HIVE-15624:
---------------------------------------
Summary: sometimes (with schema evolution?) padded char values
cannot be converted to integers
Key: HIVE-15624
URL: https://issues.apache.org/jira/browse/HIVE-15624
Project: Hive
Issue Type: Bug
Reporter: Sergey Shelukhin
Noticed while fixing HIVE-15558
Schema evolution non-vectorized tests, or maybe their previous version on 2.1,
in some instances have nulls in query results for values that are padded due to
being char (e.g. '50000' or '-9999' are converted, but '17 ' cannot be
converted and becomes null).
HIVE-15558, while restoring proper padding to char, also made vectorization
consistent with non-vectorized Hive in making them null, however that is not a
desirable behavior.
I've tried it out in simple queries with casts, and it doesn't happen ('17 '
of type char(5) is cast to int as expected).
I think we should fix this behavior for both vectorized and non-vectorized case.
