I am trying to run a M/R job remotely on a HBAse table.
I have added the conf.set("fs.default.name","hdfs://10.0.0.3:60000") to the
code hence now it does go to the cluster there I see the error
WARN org.apache.hadoop.ipc.HBaseServer: IPC Server listener on 60000:

and at the client side I see

etc
I am pretty sure I am missing configuration pieces to achieve the same..What
could be those ?
