------------------------------------
Summary: A an option to debug runnables
Key: TWILL-70
URL: https://issues.apache.org/jira/browse/TWILL-70
Project: Apache Twill
Issue Type: New Feature
Components: yarn
Reporter: Andreas Neumann
Trouble-shooting distributed apps is hard. One of the challenges is to see what
is going on inside a runnable. This will add the ability to attach a remote
debugger to a Twill runnable.: An option to start some or all runnables with
the debugging port open. The port cannot be fixed because that could cause
conflicts between multiple runnables. Therefore the runnable detects a free
port and uses that, and communicates that port back to the client via the run
resources call of the controller.
