Add simulated data node cluster start/stop commands in hadoop-dameon.sh .
-------------------------------------------------------------------------
Key: HDFS-692
URL: https://issues.apache.org/jira/browse/HDFS-692
Project: Hadoop HDFS
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
