Few questions:

1. What do you mean by a "Tomcat context"? The HDFS core daemons (NN,
DN, SNN, etc.) use Jetty to deploy their HTTP servlets, not Tomcat.
2. Did you run a build on your install and are using a built classpath
instead of the installed one?

In any case, if your problem is specific to CDH packages, please send
your mail with more details on your packages/setup instead to

Alright.. The issue was with packaging.. If you have the pig jar in the classpath, it messes up
