Description

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.

bin/hadoop-daemon.sh start org.apache.hadoop.hdfs.DataNodeCluster  -simulated -n $DATANODE_PER_HOST -inject $STARTING_BLOCK_ID $BLOCKS_PER_DN  

bin/hadoop-daemon.sh stop org.apache.hadoop.hdfs.DataNodeCluster  -simulated  

For better user interface we should add DataNodeCluster start stop option in hadoop-daemon.sh
