    [ https://issues.apache.org/jira/browse/HIVE-1853?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12972327#action_12972327

Ashutosh Chauhan commented on HIVE-1853:
----------------------------------------

Was doing some testing for HIVE-1696 test cases now fail with
{code}
 <error message="listMPartitionsByFilter is not supported due to a JDO library downgrade"
type="java.lang.RuntimeException">java.lang.RuntimeException: listMPartitionsByFilter is
not supported due to a JDO library downgrade

        at org.apache.hadoop.hive.metastore.TestHiveMetaStore.testPartitionFilter(TestHiveMetaStore.java:1065)
{code}

May be for time being (until underlying issue is fixed) we shall also disable the failing
tests so that trunk is buildable with passing all tests.

>            Reporter: Namit Jain

>             Fix For: 0.7.0

>
> 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.
