Eugene Koontz commented on GIRAPH-840:
--------------------------------------
Pavan,
Impressive, looks like a lot of work went into this!
Avery,
{{mvn -P2.2.0 test}}
and
{{mvn -Phadoop_yarn -Dhadoop.version=2.2.0 test}}
work for me, provided I use Pavan's patch from this issue together with my
GIRAPH-841 patch.
I have not yet looked at the SASL-specific tests, but I assume those passed if
the whole thing passes. Will look more at it later tonight.

> Off late netty 4 has earned so much praise in the community. For example,
> https://blog.twitter.com/2013/netty-4-at-twitter-reduced-gc-overhead
> A switch to netty 4 enables a significant reduction in gc pressure and also
> huge performance gains. I started working on this last Sunday and have a
> patch that shows performance gains on the order of 15-25% (total execution
> time) for some applications at Facebook. However, I only tested it with
> hadoop_facebook. So there might be issues with SASL path.
> I will release the patch today and want to open up a discussion if anyone is
> using the secure feature anymore. If not we can just deprecate it.
