Interesting. So it seems I actually got it to add another directory. These were the steps I followed: I ran your commands above mkdir /data/hdfs/data chmod -R 755 /data/hdfs/data sudo chown -R hdfs /data/hdfs/data After running those commands I moved to Ambari. Moved to the HDFS service. From there instead of using a comma to separate the two, I just put the new directory on a separate line underneath so it looked like: /hadoop/hdfs/data /data/hdfs/data After this I Ambari asked me to restart a few of the components. (It was taking a while so I ended up rebooting the Sandbox) After rebooting the Sandbox I went back to the Ambari config and the new directory I added earlier was still present. EDIT: Try removing the space after the comma. Ambari gave me an error when there was a space after the comma. ... View more

Hi there! Tutorial updates and improvements are in the works. You can try the tutorial here: https://github.com/ZacBlanco/hwx-tutorials/blob/securing-hadoop-with-knox-import/2-3/tutorials/securing-hadoop-infrastructure-with-apache-knox/securing-hadoop-infrastructure-with-apache-knox.md If you want to interact directly with WebHDFS you can circumvent Knox by using the WebHDFS URL instead (I believe it should be something like http://localhost:50070/webhdfs/v1/ This tutorial uses Apache Knox and WebHDFS to write some files to a directory. It utilizes `curl` on the command line to do most of the work. Please let me know if you have any feedback or questions on this one. If you're looking for more tutorial related to specific topics please let me know and I can do my best to point you in the right direction ... View more
