Paul Yang commented on HIVE-1853:
---------------------------------
The bug is that get_table (and likely get_partition) returns null even though
the object clearly exists. This is without any pruning or filtering.
Since the bug is within the newer version JDO/datanucleus, and HIVE-1609
(listPartitionsByFilter) depends on the newer version, it wouldn't have worked
with the JDO downgrade.
This patch undoes HIVE-1660, reverts JDO back to the older version, and
disables listPartitionsByFilter().

> Project: Hive
> Issue Type: Bug
> Affects Versions: 0.7.0
> Reporter: Namit Jain
> Assignee: Paul Yang
> Fix For: 0.7.0

> Attachments: HIVE-1853.1.patch, HIVE-1853.2.patch

>
> 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.
