Fengdong Yu commented on HDFS-6267:
-----------------------------------
Thanks Andrew. yes, this upgrade is not easy.
bq.. It'd be technically fine to do this in trunk for 3.0 (like this JIRA's
affects version indicates), but I personally am against divergence between
trunk and branch-2 until there's a clear plan for releasing a Hadoop 3.0
I agree, this issue will be pending to commit until there is branch-3.
bq.This is also a change that would need a lot of testing, since Jetty is used
in a lot of places in Hadoop.
Jetty was only used for webHDFS in branch-2, the new webUI is also use webHDFS,
MR shuffle use netty now.
and I did lots of tests for Jetty9 manually on my testing cluster, it works
well.

> Jetty stable version is 9.x, but it requires Java7, so I want to target 3.0

> Jetty9 is incompatible with Jetty6, so the patch will be big.
