Subject [jira] [Commented] (HIVE-13991) Union All on view fail with no valid permission on underneath table
Date Fri, 24 Jun 2016 13:42:16 GMT

    [ https://issues.apache.org/jira/browse/HIVE-13991?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15348278#comment-15348278

Yongzhi Chen commented on HIVE-13991:
-------------------------------------

init(true); combined with genResolvedParseTree() do the step one work, so assign mergeIsDirect
in init(boolean) is fine. You can think it is the same reason as clear pruned partitions or
not.
There are only two places in our code that calls genResolvedParseTree() , list it may help
you understand the code:
{noformat}
          if (reAnalyzeAST) {
            init(true);
            prunedPartitions.clear();
            // Assumption: At this point Parse Tree gen & resolution will always
            // be true (since we started out that way).
            super.genResolvedParseTree(ast, new PlannerContext());
{noformat}
