	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.
