>             Project: Hive
>          Issue Type: Bug
>    Affects Versions: 0.13.1

> If there are SHARED locks on default database. CREATE TEMPORARY FUNCTION will hang until the operation completes or until lock acquisition timeout is reached. 
> == General Reproduction Steps ==
> 1. Create a table in default. 
> 2. Do a query against that table that last a long time. I achieved this by creating a UDF that does sleep for 100 minutes. 
> 3. Try to create temporary function in another Hive CLI session. This should hang waiting for a ZK exclusive lock on default. 
> == Script Details ==
> - Works only out of box on CDH with parcels. If you are not using parcels then you need to modify paths in builder.sh.
