Description

The hive exec jar includes exploded thrift, json, and commons lang classes. These may conflict with the user's classpath. This could be fixed by jar jaring or using shade. A mechanism that allowed a user to substitute alternative versions w/o recompiling might be a useful intermediate step (though will require the user substitute alternative versions that work w/ Hive).
