+1 from me too. We've had this in CDH since Sep '11 and been working
much better than the stock 6.1.26.

I am +1 on this also, although I think we need to look at moving to
Jetty-7 or possibly dropping Jetty completely and look at Netty or even
Tomcat long term. Jetty has just been way too unstable at Hadoop scale
and that has not really changed with newer versions of Jetty. Sticking
with an old forked unsupported version of Jetty longterm seems very risky
too me.

One question I did have on this is if anyone is now seeing more jetty issues on the datanode with possibly increased usage via webhdfs - do we need something similar to https://issues.apache.org/jira/browse/MAPREDUCE-3184 on the datanode side?

I agree that we should explore alternatives the forked version of Jetty.
This is a longer term goal. In the interim, lets do jetty-6.1.26 + fixes.

In 2.0 we've reimplemented the shuffle using Netty for a significant speed up. Moving webhdfs to Netty would be interesting.
