Eli Collins commented on HIVE-2424:
-----------------------------------
bq. This would require users to add the jars to their classpath, which they're
likely already doing as they're included in the lib directory with other
necessary dependencies.
Does the lib directory get bundled up and shipped with hive-exec? I assumed the
motivation for the fat-jar was:
# You only have to submit hive-exec
# Can't assume the same classes with the proper versions are in the MR classpath
> 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).
