node maintenance

Places a node into a maintenance mode for a specified duration.

Important: Stop CLDB if it is running on the node, before putting that node in maintenance mode. Else, the maintenance mode operation is not permitted. Run: maprcli node services -name cldb -action stop -nodes mapr-<node>

Note: You cannot put a master CLDB node in Maintenance mode.

For the duration of the maintenance mode, the cluster's CLDB does not consider the data of this node as lost and does not trigger a resync of the data on this node. See Administering Nodes for more information.
