Subject [jira] [Created] (MAPREDUCE-4015) Yarn services to throw a YarnException on invalid state changs
Date Thu, 15 Mar 2012 16:19:38 GMT
Yarn services to throw a YarnException on invalid state changs
--------------------------------------------------------------

                 Key: MAPREDUCE-4015
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-4015
             Project: Hadoop Map/Reduce
          Issue Type: Sub-task
          Components: mrv2
    Affects Versions: 0.23.1, 0.24.0
            Reporter: Steve Loughran
            Assignee: Steve Loughran
            Priority: Minor


the {{EnsureCurrentState()}} checks of services throw an {{IllegalStateException}}  if the
state is wrong. If this was changed to {{YarnException}}. wrapper services such as CompositeService
could relay this direct, instead of wrapping it in their own.

Time to implement mainly in changing the lifecycle test cases of MAPREDUCE-3939 subtasks.
