 Description   

Since the Jepsen task (java process) will occasionally hang, we need to add the java process to the hang_analyzer.py. A good way to do this is the parameterize the list of tasks to analyze and have the task define that list and use that as an option by the hang_analyzer.py script.

Note - jstack is in the package openjdk-8-jdk.

Comment by Michael O'Brien [ 06/Jun/16 ]

If it's a java process, then the typical hang_analyzer procedure probably won't generate any useful output. We may need to get the java stack trace using kill -3 or jstack or maybe there is something better for clojure specifically.
