1. Prerequisites

  • Ensure that you have deployed HDP for all the nodes in your cluster. For instructions on deploying HDP, see “Getting Ready to Install” in Installing HDP Using Apache Ambari here.

  • Ensure that you create a home directory for the user launching the TOS in the HDFS cluster.

    EXAMPLE:

    If hdptestuser is responsible for launching TOS, then execute the following command on the gateway machine as the administrator user (HDFS user) to create home directory:

    % hadoop dfs –mkdir /user/hdptestuser
              
  • Ensure the user launching the TOS has appropriate permissions on the HDP cluster.

    EXAMPLE:

    If hdptestuser is responsible for launching TOS, then execute the following command on the gateway machine as the administrator user (HDFS user) to provide the required permissions:

    % hadoop dfs –chown hdptestuser:hdptestuser /user/hdptestuser
