> Improve YARN RM REST API error messages
> ---------------------------------------
>
> Key: YARN-3550
> URL: https://issues.apache.org/jira/browse/YARN-3550
> Project: Hadoop YARN
> Issue Type: Bug
> Components: webapp
> Affects Versions: 2.6.0
> Reporter: Rajesh Kartha
> Priority: Minor
>
> The error messages from an invalid REST call to the YARN RM Rest service does
> not yield in useful messages.
> Here is a simple example of using GET instead of POST to get a new
> application id:
> $ curl -X GET http://myhost:8088/ws/v1/cluster/apps/new-application
> <?xml version="1.0" encoding="UTF-8"
> standalone="yes"?><RemoteException><exception>WebApplicationException</exception><javaClassName>javax.ws.rs.WebApplicationException</javaClassName></RemoteException>
> and the RM log has this:
> 2015-04-27 11:18:27,783 WARN webapp.GenericExceptionHandler
> (GenericExceptionHandler.java:toResponse(98)) - INTERNAL_SERVER_ERROR
> javax.ws.rs.WebApplicationException
