Step 4. Create a Hadoop Connection

Step 4. Create a Hadoop Connection

Create a Hadoop connection for the Blaze instance to use.
  1. In Step 1 of the New Connection wizard, configure the Impersonation User Name property with the same impersonation user that you configured in Step 1, Create a Blaze User Account.
    The following image shows the Impersonation User Name property in the New Connection wizard:
  2. In Step 3 of the New Connection wizard, configure the Temporary Working Directory on HDFS property with the path that you configured on the cluster in "Create Blaze Engine Directories and Grant Permissions."
    The following image shows the Temporary Working Directory on HDFS property in the New Connection wizard:
  3. Configure the Blaze Service User Name property with the same user name that you used to configure the Impersonation User in Step 1 of this topic.
  4. Configure the Minimum Port and Maximum Port properties with a port range for the connection.
    You can supply a range within the port range of an existing Grid Manager, as long as ports are available when the mapping runs. The default range is 300 ports.
    The following image shows the Minimum Port and Maximum Port properties in the New Connection wizard:
