Set up HDFS user directory

Is this task necessary for Pig View ??? seems Hive-specific

The Hive View stores user metadata in HDFS. By default, the location in HDFS for this metadata is /user/$[USER_NAME] where $[USER_NAME] is the user name of the currently logged in user that is accessing the Hive View.

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

Connect to a host in the cluster that includes the HDFS client.
Switch to the hdfs system account user.
su - hdfs
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
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
