> Key: HADOOP-6383
> URL: https://issues.apache.org/jira/browse/HADOOP-6383
> Project: Hadoop Common
> 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
