Subject [jira] [Commented] (HIVE-1496) enhance CREATE INDEX to support immediate index build
Date Tue, 01 Nov 2011 03:36:32 GMT

    [ https://issues.apache.org/jira/browse/HIVE-1496?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13140886#comment-13140886

Syed S. Albiz commented on HIVE-1496:
-------------------------------------

I've been looking at this for a while, unfortunately, since the population job requires the
index table to exist so that it can do an INSERT OVERWRITE (...) into it, the approach we
discussed using a dummy object will not work as expected. I think the only way to make this
work will be to do the ms transaction to create the index table immediately in the SemanticAnalyzer,
with a special case if necessary for EXPLAINs such that the code is not executed if part of
an EXPLAIN statement.
