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.
