- Note the hostnames of the CLDB and ZooKeeper nodes. Optionally, you can specify the ports for the CLDB and ZooKeeper nodes as well. The default CLDB port is 7222. The default ZooKeeper port is 5181.
If a node in the cluster runs the HistoryServer, note the hostname for the HistoryServer. The HistoryServer node must be specified using the
If one or more nodes in the cluster runs the ResourceManager, note the hostname or IP address for each ResourceManager node. Based on the version you install and your ResourceManager high availability requirements, you may need to specify the ResourceManager nodes using the
-RMparameter. Starting in 4.0.2, high availability for the ResourceManager is configured by default and does not need to be specified. For more information, see ResourceManager High Availability.
If mapr-fileserver is installed on this node, you can use configure.sh to format the disks and setup partitions or you can manually run disksetup after you run configure.sh. For more information, see Using configure.sh to Run disksetup.
For a cluster node that is on a VM, use the
--ipvmparameter when you run configure.sh, so that the script uses less memory.
Starting in MapR version 4.0.1, the MapR Community Edition and the MapR Enterprise Database Edition licenses both provide read/write access to MapR-DB tables. The MapR Enterprise Edition license provides read-only access to MapR-DB tables. If you do not plan to access MapR-DB on your cluster, run configure.sh with the
-noDBparameter on each node. This results in less memory being allocated to MFS, and more memory being allocated to MapReduce services.
