Subject [jira] Commented: (HIVE-1853) downgrade JDO version
Date Thu, 16 Dec 2010 23:15:01 GMT

    [ https://issues.apache.org/jira/browse/HIVE-1853?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12972280#action_12972280

Namit Jain commented on HIVE-1853:
----------------------------------

Ashutosh, what is your timeline ?

Right now, we dont have the infra-structure in place to pick some patches and ignore others.
We pick all the patches from the open source to our internal tree.

For the time it will take us to develop this, can you live with the current trunk 
(lower JDO) ?

> After HIVE-1609, we are seeing some table not found errors intermittently.
> We have a test case where 5 processes are concurrently issueing the same query - 
> explain extended insert .. select from <T>
> and once in a while, we get a error <T> not found - 
> When we revert back the JDO version, the error is gone.
> We can investigate later to find the JDO bug, but for now this is a show-stopper for
facebook, and needs
> to be reverted back immediately.
> This also means, that the filters will not be pushed to mysql.
