Description

Currently, we are using Jetty version 9.2.16.v20160414.

However, Hadoop 3, uses 9.3.11.v20160721 (Jetty upgrade was brought in by HADOOP-10075).

Currently, when you try to build Spark with Hadoop 3, due to this incompatibilities in jetty versions used by Hadoop and Spark, compilation fails with:

[ERROR] source/core/src/main/scala/org/apache/spark/ui/JettyUtils.scala:31: error: object gzip is not a member of package org.eclipse.jetty.servlets
[ERROR] import org.eclipse.jetty.servlets.gzip.GzipHandler
[ERROR]                                   ^
[ERROR] source/core/src/main/scala/org/apache/spark/ui/JettyUtils.scala:238: error: not found: type GzipHandler
[ERROR]       val gzipHandler = new GzipHandler
[ERROR]                             ^
[ERROR] two errors found

So, it'd be good to upgrade Jetty to get us closer to working with Hadoop 3.
