Edward Capriolo commented on HIVE-2424:
---------------------------------------
I feel we are going to need them. I believe originally this was done because
libjars was inconsistent between hadoop version. However I do not think you can
not take them out. Hive needs these things to work. If you took them out from
the hive-exec build and provided them with libjars you would still end up with
a conflict when adding your jars. (I could be wrong)
> Don't expose thrift, commons and json classes in the hive exec jar

> 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).
