Description

It would be nice to have a way to attach a debugger to the miniclusters: http://cargo.codehaus.org/Starting+and+stopping+a+container.

For tomcat, I needed to add the following to TomcatSqoopMiniCluster:

configuration.setProperty(GeneralPropertySet.JVMARGS, "\"-agentlib:jdwp=transport=dt_socket,server=y,suspend=y,address=5005\"");

There should also be a way to attach a debugger to the Yarn container.
