---------------------------------

             Summary: Max app start time should be configurable.
                 Key: TWILL-187
                 URL: https://issues.apache.org/jira/browse/TWILL-187
             Project: Apache Twill
          Issue Type: Improvement
            Reporter: Albert Shau


The YarnTwillController waits at most 60 seconds (Constants.APPLICATION_MAX_START_SECONDS) for the app master to start up before killing the app. This number should be configurable instead of hardcoded. For example, it is a fairly common use case to schedule programs to run at regular intervals in a cluster. If a bunch of programs are started at the same time, this time out can be easily reached.

On a small development cluster, I've reached this timeout if there are 30-40 concurrent program starts.
