Hive NPE under Tez only if UDF used.

 Hi,
Here is a strange error with hive under Tez.  I am using hive-0.13.0 and tez-0.5-snapshot

I can run Hive job successful under tez without UDF used. 
I can run tez MR example job successful  under tez.

but there is hive job NPE under tez with UDF used.

java.lang.NullPointerException

Fixed.
 
Sorry, It's my fault. I hacked Hadoop major version in my test cluster as 1.3.0, actually it was 2.4.0.
But ShimLoader parse major version as 1, so get HDFSv1 FileSystem. then I get this error.
