Test scenarios :

1) Put a healthy slave task tracker in the dfs.exclude file.

2) As a valid user, decommission a  node in the cluster by issuing the command "hadoop mradmin
-refreshNodes"

3) Make sure that the node is decommissioned.

4) Now take the task tracker out of the file.

5) As a valid user, again issue the command "hadoop mradmin -refreshNodes"

6) Make sure that the node is not in the decommiossion list.

7) Bring back that node.
