Steve Loughran commented on HADOOP-9244:
----------------------------------------
This is part of a combined update relating to HADOOP-9613 -jersey, HADOOP-10076
- tomcat, & HADOOP-10075 - jetty.
I don't think we should update things in isolation, especially the servlet
interface definition *which is not completely implemented in Jetty 6*.
Maybe we should create a single JIRA to cover the update "move the servlet API
and implementations up". Then update in trunk & decide whether or not to
backport. Now that MapReduce doesn't use Jetty, Hadoop should be less sensitive
to these dependencies being changed
> Upgrade servlet-api dependency from version 2.5 to 3.0.

> Please update the servlet-api jar from 2.5 to javax.servlet 3.0 via Maven:
> <dependency>
> <groupId>javax.servlet</groupId>
> <artifactId>javax.servlet-api</artifactId>
> <version>3.0.1</version>
> <scope>provided</scope>
> </dependency>
> I am running a 2.0.3 dev-cluster and can confirm compatibility. I have
> removed the servlet-api-2.5.jar file and replaced it with
> javax.servlet-3.0.jar file. I am using javax.servlet-3.0 because it
> implements methods that I use for a filter, namely the
> HttpServletResponse.getStatus() method.
> I believe it is a gain to have this dependency as it allows more
> functionality and has so far proven to be backwards compatible.
