Subject [yarn] job is not getting assigned
Date Thu, 29 Aug 2013 14:52:52 GMT

I am in the middle of setting up a hadoop 2 cluster. I am using the hadoop
2.1-beta tarball.

My cluster has 1 master node running the hdfs namenode, the resourcemanger
and the job history server. Next to that I have  3 nodes acting as
datanodes and nodemanagers.

In order to test, if everything is working, I submitted the teragen job
from the hadoop-examples jar like this:

$ hadoop jar
teragen 1000 /user/vagrant/teragen

The job starts up and I  get the following output:

13/08/29 14:42:46 WARN util.NativeCodeLoader: Unable to load native-hadoop

and then it stops. If I check the UI, I see this:

vagrantTeraGenMAPREDUCEdefaultThu, 29 Aug 2013 14:42:49 GMTN/AACCEPTED

UNASSIGNED <http://master.local:8088/cluster/apps#>
I have no idea, why it is not starting, nor what to look for. Any pointers
are more than welcome!
