Step 2. Verify Connection to the Hadoop Cluster

Step 2. Verify Connection to the Hadoop Cluster

After you install the HDFS client libraries, verify the connection to the Hadoop cluster. Verify the NameNode and port on which the NameNode listens for connections.
To verify the HDFS connection, run the following command from the command prompt on the data target machine:
$HADOOP_HOME/bin/hadoop fs -ls hdfs://<namenode-name>[:<port>]/
Where
  • HADOOP_HOME
     is the Hadoop installation directory.
  • namenode-name
     is the host name or IP address of the NameNode.
  • port
     is the port number on which the NameNode listens for connections.
