Gopal V commented on HIVE-6346:
-------------------------------

Sure.

I just did some testing with hadooo-2.2.x release with zero-copy reads config 
option turned on, with a build compiled against 2.4.0. The feature gets turned 
off automatically without any class loader errors.

> Add Hadoop-2.4.0 shims to hive-tez
