Robert Kanter commented on HADOOP-14930:
----------------------------------------
Jetty moved a number of things, some that we're using and are updated in the
patch, from {{SessionManager}} to {{SessionHandler}}. This means that
upgrading Hadoop from Jetty 9.3.x to 9.4.x is going to also force _all_
downstream projects to also upgrade to Jetty 9.4.x. Are we okay with that?
