Re: Requesting containers on a specific host
I could resolve this error with a simple host name change to a fully qualified one including the domain name. But to go ahead running some of my old example code, I am observing at least the following changes : 1) ClientRMProtocol and AMRMProtocol are removed. 2) ContainerManager is removed. 3) YarnRemoteException is removed. 4) ContainerRequest is removed. It looks like it is now compulsory to modify my application accordingly, where as on earlier versions, I could have run the same application without any modifications.

Re: Requesting containers on a specific host
Hi Kishore, As per the exception given, Node Manager is getting excluded. It might be happening that you have configured the Node Manager in excluded file using this configuration in Resource Manager. Could you check this configuration in RM, is it configured with any file and that file contains the NM address? property descriptionPath to file with nodes to exclude./description nameyarn.resourcemanager.nodes.exclude-path/name value/value /property and also can you cross check this configuration, if you have updated this then the modification is proper or not. property descriptionPath to file with nodes to include./description nameyarn.resourcemanager.nodes.include-path/name value/value /property ThanksRegards Devaraj k -- View this message in context: http://lucene.472066.n3.nabble.com/Requesting-containers-on-a-specific-host-tp4072089p4075779.html Sent from the Hadoop lucene-users mailing list archive at Nabble.com.

Re: Requesting containers on a specific host
Hi Arun, I just found that setHostName() doesn't work on 2.0.0-alpha and works on 2.0..4-alpha, I didn't check the intermediate versions. I have verified it by starting the daemons of respective versions, and modifying the ApplicationMaster.java in the distributed shell example, and running a date command on it. Is this something already known? or have I been doing something wrong?
