Jason Lowe commented on TEZ-3902:
---------------------------------
Here's a patch that updates the netty version per my discussion above. The
only difference in the dist tarballs after this change is that
tez-ext-service-tests.jar and netty-3.6.2.Final.jar are missing from the
minimal tarball after this change. I have not had any time to test this. I
verified it builds successfully and does what I believe is desired as far as
removing the netty jar that is conflicting with Hive and Hadoop 3.
I *think* this is a safe change for Hadoop 2.x as well, since we're not
changing the version of a jar we're shipping in the minimal build but rather
relying on the netty version we get from Hadoop.
> Upgrade to netty-3.10.5.Final.jar
