     [ https://issues.apache.org/jira/browse/HIVE-1546?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Ashutosh Chauhan updated HIVE-1546:
-----------------------------------

    Attachment: hive-1546-4.patch

After some recent changes, It seems its necessary to do
{code}
conf.set(HiveConf.ConfVars.HIVE_SUPPORT_CONCURRENCY.varname, "false");
{code}
in the test-case, otherwise test-case just hangs. Added it in my test-case. No other changes in the patch (as compared to previous patch) otherwise.

> It will be useful if Semantic Analysis phase is made pluggable such that other projects can do custom analysis of hive queries before doing metastore operations on them.
