---------------------------------------

             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.
