Alejandro Abdelnur commented on HADOOP-9301:
--------------------------------------------

The patch I'm working on (more on that after in the next paragraph) disable=
s transitive dependencies that are not required, we have to do that one by =
one when we verify that they are not needed on the client side.

I've spent a good chunk of the day trying to validate my patch (using the r=
esulting hadoop-client JARs in Oozie) but I'm running into other issues bet=
ween Hadoop trunk and Oozie 3.3.1, thus have to diagnose that too.

> Here's how to reproduce:
> {noformat}
> $ cd hadoop-client
> $ mvn dependency:tree | egrep 'jsp|jetty'
> [INFO] |  +- org.mortbay.jetty:jetty:jar:6.1.26.cloudera.2:compile
> [INFO] |  +- org.mortbay.jetty:jetty-util:jar:6.1.26.cloudera.2:compile
> [INFO] |  +- javax.servlet.jsp:jsp-api:jar:2.1:compile
> {noformat}
> This has a potential for completely screwing up clients like Oozie, etc =
=E2=80=93 hence a blocker.
> It seems that while common excludes those JARs, they are sneaking in via =
hdfs, we need to exclude them too.
