2. Smoke Test HDFS

  1. See if you can reach the NameNode server with your browser:

    http://{namenode.full.hostname}:50070
  2. Try copying a file into HDFS and listing that file:

    Login as $HDFS_USER
    /usr/lib/hadoop/bin/hadoop dfs -copyFromLocal /etc/passwd passwd-test
    /usr/lib/hadoop/bin/hadoop dfs -ls
  3. Test browsing HDFS:

    http://$datanode.full.hostname:50075/browseDirectory.jsp?dir=/
