Sushanth Sowmyan commented on HIVE-8257:
----------------------------------------

[~vikram.dixit], could you please check this patch to see if this is okay? (It seems correct
to me, but I also remember something about subcomponents having to depend on the right version
of shims, and shims bringing in deps instead - I'm not sure if that changed)

> It was brought to my attention that Accumulo is transitively bringing in some artifacts
with the wrong version of Hadoop.
> Accumulo-1.6.0 sets the Hadoop version at 2.2.0 and uses hadoop-client to get its necessary
dependencies. Because there is no dependency with the correct version in Hive, this introduces
hadoop-2.2.0 dependencies.
> A solution is to make sure that hadoop-client is set with the correct {{hadoop-20S.version}}
or {{hadoop-23.version}}.
> Snippet from {{mvn dependency:tree -Phadoop-2}}
