useExistingCluster

public static Long useExistingCluster

(boolean) whether or not to use an existing cluster (e.g. Isilon) Defaults to false.

manageMapReduceComponents

public static Long manageMapReduceComponents

(boolean) When running with an existing cluster (vs. starting the hadoop cluster), start mapreduce hadoop components (ResourceManager and NodeManager). Used with Isilon HDFS File System boxes (since we must still run the mapreduce components) Defaults to true.
