*** Instructions to start the Namenode & Datanodes ***

Namenode

1/ Set the JAVA_HOME environment variable
2/ Unzip the jxtadoop-datanode-x.y.z.zip to the target directory

        + chmod the executable in bin/ directory
3/ Edit the etc/hdfs-p2p.xml and set the following 2 properties :
        hadoop.p2p.rpc.rdv
        hadoop.p2p.rpc.relay 
    Note that this 2 properties are mandatory even if the same multicast network
    to avoid issues with multiple namenodes running in the same network.
4/ Initiliaze the namenode : 
        > bin/hadoop namenode -format
5/ Start up the namenode
        > bin/start-namenode.sh

Datanode

1/ Set the JAVA_HOME environment variable
2/ Unzip the jxtadoop-datanode-x.y.z.zip to the target directory

        + chmod the executable in bin/ directory
3/ Edit the etc/hdfs-p2p.xml and set the following 2 properties :
        hadoop.p2p.rpc.rdv
        hadoop.p2p.rpc.relay
4/ Start up the namenode
        > bin/start-datanode.sh

DFSClient

You can use the DFSClient as per Hadoop. For example

bin/hadoop fs -mkdir /test
bin/hadoop fs -chmod 777 /test
bin/hadoop fs -put ~/tmp/myfile /test
bin/hadoop fs get /test/myfile /tmp
