You can install the MapR distribution for Hadoop on a set of nodes from any machine that can connect to the nodes. Using the quick installer, you can configure each node in a MapR cluster as one of the following types:<br /> <br /> *&#039;&#039;&#039;Control Node:&#039;&#039;&#039; Control nodes manage the operation of the cluster. Control nodes host the ZooKeeper, CLDB, JobTracker, ResourceManager, and Webserver services. One control node also hosts the HistoryServer.<br /> *&#039;&#039;&#039;Data Nodes:&#039;&#039;&#039; Data nodes host the NodeManager, TaskTracker, and FileServer services. These nodes store data, run YARN applications and MapReduce jobs, and process table data.<br /> *&#039;&#039;&#039;Control-as-Data Nodes:&#039;&#039;&#039; Control-as-data nodes combine control and data node functionality. This node type is appropriate for small clusters.<br /> *&#039;&#039;&#039;Client Nodes:&#039;&#039;&#039; Client nodes provide controlled user access to the cluster.</div>
