web proxy returns internal server error when application invalid
----------------------------------------------------------------
Key: MAPREDUCE-3551
URL: https://issues.apache.org/jira/browse/MAPREDUCE-3551
Project: Hadoop Map/Reduce
Issue Type: Bug
Components: mrv1
Affects Versions: 0.23.0
Reporter: Thomas Graves
Priority: Critical
querying for an absent app i.e. say
http://RM:8088/proxy/application_1323054018624_0004/ws/v1/mapreduce/info -
returns a 500 with a stack trace instead of a 404. From an api spec point of
view, this is not really an error but just a not found. This occurs with web
services as well as any web ui page.
