>          Issue Type: Improvement
>            Reporter: Ravi Phulari
>
> Currently there are no commands supported for starting or stopping simulated data node
clusters.
> To start simulated data node cluster we need to export extra class paths required for
DataNodeCluster.

> {noformat}
> bin/hadoop-daemon.sh start org.apache.hadoop.hdfs.DataNodeCluster  -simulated -n $DATANODE_PER_HOST
-inject $STARTING_BLOCK_ID $BLOCKS_PER_DN  
> {noformat}
> {noformat}
> bin/hadoop-daemon.sh stop org.apache.hadoop.hdfs.DataNodeCluster  -simulated  
> {noformat}
> For better user interface we should add DataNodeCluster start stop option in hadoop-daemon.sh
