Guanghao Zhang commented on HBASE-19349:
----------------------------------------
{code}
<!--
Note: There are a few exclusions to prevent duplicate code in different
jars to be included:
org.mortbay.jetty:servlet-api, javax.servlet:servlet-api: These are
excluded because they are
the same implementations. I chose org.mortbay.jetty:servlet-api-2.5
instead, which is a third
implementation of the same, because Hadoop also uses this version
javax.servlet:jsp-api in favour of org.mortbay.jetty:jsp-api-2.1
-->

I saw this comment in pom.xml. This comment seems outdated and can be removed
too? [~stack]

> Affects Versions: 2.0.0-beta-1
> Reporter: Guanghao Zhang
> Priority: Critical

> Build a tarball.
> {code}
> mvn -DskipTests clean install && mvn -DskipTests package assembly:single
> tar zxvf hbase-2.0.0-beta-1-SNAPSHOT-bin.tar.gz
> {code}
> Then I found there is a servlet-api-2.5.jar in the lib directory. The right
> depencency should be javax.servlet-api-3.1.0.jar.
> Start a distributed cluster with this tarball. And got exception when access
> Master/RS info jsp.

> Try mvn depencency:tree but didn't find why servlet-api-2.5.jar was
> introduced.
> I download hbase-2.0.0-alpha4-bin.tar.gz and didn't find servlet-api-2.5.jar.
> And build a tar from hbase-2.0.0-alpha4-src.tar.gz and didn't find
> servlet-api-2.5.jar, too. So this may be introduced by recently commits. And
> should fix this when release 2.0.0-beta1.
