Unable to launch apache twill within hortonworks sandbox and eclipse

Question

I can not get my development environment up and running a simple twill application within the hortonworks sandbox and eclipse.

I can get everything to compile but I end up running into this error when I launch it within eclipse.

Answer 1

It looks like it is caused by incompatible Hadoop version. You can check the Hadoop version in the sandbox vs the version used in Eclipse.
