7. Start the Installation

  1. As root user, execute the following command:

    sh master-install-location/gsInstaller/gsInstaller.sh

  2. Confirm the set-up properties. (Type y or Y and press Enter.)

    This step launches the HDP Installer. Depending on the number of nodes in your cluster, this step can take couple of minutes to complete the smoke tests.

    [Note]Note

    The value of NameNode new generation size (default size of Java new generation for NameNode (Java option -XX:NewSize)) should be 1/8 of maximum heap size (-Xmx). To change the default setting, modify the namenode_opt_newsize property in the master-install-location/gsInstaller/gsCluster.properties file. Ensure that the value of the namenode_opt_newsize property is 1/8 the value of maximum heap size (-Xmx). For more details on gsCluster.properties file, see Configuration Cluster Properties. Also ensure that your NameNode and secondary NameNode have identical memory settings.
