Subject Re: Invalide URI in job start
Date Mon, 27 Jan 2014 19:00:10 GMT
Need your help to debug this. Seems like the scheme is getting lost somewhere along the way.
Clearly as you say if job.jar is on the file-system, then JobClient is properly uploading
it. There are multilple things that you'll need to check
 - Check the NodeManager logs for the URL. It does print what URL it is trying to download
from. Check if the scheme is getting there or not.
 - If that doesn't tell you something, change JobClient to print the URL before it constructs
the ContainerLaunchContext for the ApplicationMaster. You'll need to do this in YarnRunner.java.
Specifically the method createApplicationResource.

Thanks,

FileSystem implementation for Hadoop 1.x that works fine. First think I did was to implement
a DelegateToFileSystem subclass to provide an AbstractFileSystem implementation for XtreemFS
(just constructors that use the FileSystem implementation). When I start the wordcount example
application I get the following Exception on the NodeManager:
