Removing a Node Using the MapR CLI

Before you start, drain the node of data by moving the node to the /decommissioned physical topology.

All the data on a node in the/decommissioned topology is migrated to volumes and nodes in the /data topology Use the node remove command to remove one or more server nodes from the cluster. To run this command, you must have full control (fc) or administrator (a) permission. The syntax is:

maprcli node remove
    [ -filter "<filter>" ]
    [ -force true|false ]
    [ -hostids <host IDs> ]
    [ -nodes <node names> ]
    [ -zkconnect <ZooKeeper Connect String> ]

After you issue the node remove command, wait several minutes to ensure that the node has been completely removed.
