[jira] [Comment Edited] (HIVE-15351) Disable vectorized VectorUDFAdaptor usage with non-column or constant parameters

    [ https://issues.apache.org/jira/browse/HIVE-15351?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15723396#comment-15723396 ]

orc_ppd_schema_evol_3a.q is a flakey test.

The others are from queries that no longer vectorize due to the change.  Updating patch.

> Vectorization using VectorUDFAdaptor is broken and produces wrong results when the parameter(s) have vectorized expressions that allocate scratch columns.  So, for now, we restrict VectorUDFAdaptor usage to columns or constant expressions.
