Hadoop TaskTrackers on EC2 mix of internal and external host names
------------------------------------------------------------------

                 Key: WHIRR-492
                 URL: https://issues.apache.org/jira/browse/WHIRR-492
             Project: Whirr
          Issue Type: Bug
          Components: service/hadoop
    Affects Versions: 0.7.0
         Environment: EC2
            Reporter: Tim Robertson


Running a 1 master, 3 node cluster of Hadoop + HBase, I see on the Hadoop task 
trackers
the following hosts:

1) domU-12-31-39-0B-C1-81.compute-1.internal
2) ip-10-66-197-215.ec2.internal
3) domU-12-31-39-0E-F2-41.compute-1.internal

This is consistent with both the trunk (today) and 0.7.0.2, and all
tasks on node 2) above then fail.

My config is the following:
 whirr.cluster-name=hbase
 whirr.instance-templates=1
zookeeper+hadoop-namenode+hadoop-jobtracker+hbase-master,3
hadoop-datanode+hadoop-tasktracker+hbase-regionserver
 whirr.provider=aws-ec2
 whirr.identity=${env:AWS_ACCESS_KEY_ID}
 whirr.credential=${env:AWS_SECRET_ACCESS_KEY}
 whirr.hardware-id=c1.xlarge
 whirr.image-id=us-east-1/ami-da0cf8b3
 whirr.location-id=us-east-1
