+1 Thanks @bharatviswa504 the quick fix

It solves the problem quickly, but as a long-term solution we need to review the dependency graph. None of the server side components should be available from the client jar. As I see the framework (=server side common) and container service jar files are added to the ozonefs, which is bad.

But we can fix it in a separated jira as it may require more time.

Tested with unzip -l target/hadoop-ozone-filesystem-lib-current-0.5.0-SNAPSHOT.jar | grep webapp. Webapp has been disappeared.
