Jason Lowe commented on HDFS-11498:
-----------------------------------
I was under the impression this would go in relatively cleanly for branch-2.8,
but that does not seem to be the case. There is a minor conflict on some
imports in the patch, but even after those are resolved the build is broken
after this patch. DatanodeHttpServer fails to compile after the netty-all
version change. I suspect it is because HDFS-8377 was semi-reverted from
branch-2 but not branch-2.8. Seems like we need to cherry-pick the fix for
HDFS-11376 (really the revert patch in HDFS-8377) to branch-2.8 _then_ apply
this change. Thoughts?

> Per discussion in HADOOP-13866, it looks like we can change 2.8.0 back to
> exposing Netty 4.0, but still be ABI compatible with Netty 4.1 for users like
> HBase that want to swap out the version.
