Submitting a job to a remote cluster
Trying to submit a Job to a remote Hadoop instance. Everything seem to
start fine but then I am seeing this:

2012-10-04 15:56:32,617 INFO [org.apache.hadoop.mapred.JobClient] - < map
0% reduce 0%>

2012-10-04 15:56:32,621 INFO [org.apache.hadoop.mapred.MapTask] - <data

2012-10-04 15:56:32,621 INFO [org.apache.hadoop.mapred.MapTask] - <record

2012-10-04 15:56:32,641 WARN [org.apache.hadoop.hdfs.DFSClient] - <Failed
to connect to /127.0.0.1:50010, add to deadNodes and
continuejava.net.ConnectException: Connection refused>
How can I specify datanode address to use?

Thanks
