Subject [jira] [Commented] (YARN-628) Fix YarnException unwrapping
Date Fri, 17 May 2013 05:55:25 GMT

    [ https://issues.apache.org/jira/browse/YARN-628?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13660363#comment-13660363
] 

Vinod Kumar Vavilapalli commented on YARN-628:
----------------------------------------------

I also didn't like it, tried a couple of solutions, none of them work. The only solution is
creating a union (IOException, YarnRemoteException), return the union and make the callers
throw one of them explicitly.

> Unwrapping of YarnRemoteExceptions (currently in YarnRemoteExceptionPBImpl, RPCUtil post
YARN-625) is broken, and often ends up throwin UndeclaredThrowableException. This needs to
be fixed.
