> I had some trouble compiling an application (Shark) against Spark 1.0,
> where Shark had a runtime exception (at the bottom of this message) because
> it couldn't find the javax.servlet classes.  SBT seemed to have trouble
> downloading the servlet APIs that are dependencies of Jetty (used by the
> Spark web UI), so I had to manually add them to the application's build
> file:
> libraryDependencies += "org.mortbay.jetty" % "servlet-api" % "3.0.20100224"
> Not exactly sure why this happens but thought it might be useful in case
> others run into the same problem.
> {quote}
> This is a symptom of Servlet API conflict which we battled in the Maven build. The resolution is to nix Servlet 2.5 and odd old Jetty / Netty 3.x dependencies. It looks like the Hive part of the assembly in the SBT build doesn't exclude all these entirely.
> I'll open a suggested PR to band-aid the SBT build.
