Set up HDFS User Directory

Falcon View stores user metadata in HDFS. By default, the location in HDFS for this metadata is /user/${username} where ${username} is the username of the currently logged in user that is accessing Falcon View.


Since many users leverage the default Ambari admin user for getting started with Ambari, the /user/admin folder needs to be created in HDFS. Therefore, be sure to create the admin user directory in HDFS using these instructions prior to using the view.

To create user directories in HDFS, do the following for each Falcon View user:


  1. Connect to a host in the cluster that includes the HDFS client.

  2. Switch to the hdfs system account user.

    su - hdfs
  3. Using the HDFS client, make an HDFS directory for the user. For example, if your username is admin, you would create the following directory.

    hadoop fs -mkdir /user/admin
  4. Set the ownership on the newly created directory. For example, if your username is admin, you would make that user the directory owner.

    hadoop fs -chown admin:hadoop /user/admin
