Setting up a Blaze User Account

Create a user account for the Blaze engine. Use that user account to start the Blaze engine.
Perform the following steps:
    1. On every node in the Hadoop cluster, create an operating system user account.
    For example, to create a user account named "blaze", run the following command on every node in the cluster:
    useradd blaze
    2. Give the user the minimum required privileges and permissions.
    For example, the user account for the Blaze engine must be able to read from HDFS.
    3. In the Developer tool, create a Hadoop connection.
    Note: You must use user impersonation for the Hadoop connection if the Hadoop cluster uses Kerberos authentication.
    For more information about how to create a Hadoop connection, see the Big Data Management User Guide.
    4. In the connection properties, use the user account you created in step 1 for the Blaze Service User Name.
