>                 Key: SPARK-20514
>                 URL: https://issues.apache.org/jira/browse/SPARK-20514
>             Project: Spark
>          Issue Type: Bug
>          Components: Spark Core
>    Affects Versions: 2.2.0
>            Reporter: Mark Grover
>
> Currently, we are using Jetty version 9.2.16.v20160414.
> However, Hadoop 3, uses [9.3.11.v20160721|https://github.com/apache/hadoop/blob/release-3.0.0-alpha2-RC0/hadoop-project/pom.xml#L38] (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:
> {code}
> [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
> {code}
> So, it'd be good to upgrade Jetty to get us closer to working with Hadoop 3.
