MapR 5.0 Documentation : node allow-into-cluster



Allows host IDs to join the cluster after duplicates have been resolved.


When the CLDB detects duplicate nodes with the same host ID, all nodes with that host ID are removed from the cluster and prevented from joining it again. After making sure that all nodes have unique host IDs, you can use the node allow-into-cluster command to un-ban the host ID that was previously duplicated among several nodes.
