stack commented on HBASE-7104:
------------------------------
+1 on patch. The exclusion works for h1. We need to figure how to do
exclusion for h2 too. Its harder because there are multiple jars included and
maven doesn't let you do xinclude or the like so you'd have to repeat the
(large) exclusion set for each of the hadoop2 jars listed (least that is how it
seems to me currently).
> HBase includes multiple versions of netty: 3.5.0; 3.2.4; 3.2.2

> The patch attached:
> - fixes this for hadoop 1 profile
> - bump the netty version to 3.5.9
> - does not fix it for hadoop 2. I don't know why, but I haven't investigate:
> as it's still alpha may be they will change the version on hadoop side anyway.
> Tests are ok.
> I haven't really investigated the differences between netty 3.2 and 3.5. A
> quick search seems to say it's ok, but don't hesitate to raise a warning...
