Stephan Ewen commented on FLINK-3952:
-------------------------------------
True, only Hadoop's netty is shaded.
We should be able to shade Flink's Netty as well. Upgrading it to 4.1 seems
harder.
It is always an issue if libraries bread their backwards compatibility within a
major version :-(
> Bump Netty to 4.1

> Netty 4.1 is about to release final. This release has [a number of
> significant
> enhancements|http://netty.io/wiki/new-and-noteworthy-in-4.1.html], and in
> particular I find HTTP/2 codecs to be incredibly desirable to have.
> Additionally, hopefully, the [Hadoop patches for Netty
> 4.1|https://issues.apache.org/jira/browse/HADOOP-11716] get some tests and
> get merged, & I believe if/when that happens it'll be important for Flink to
> also be using the new Netty minor version.
