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