When first setting up a five node cluster, we were able to install the datanode, add the new node to the cluster.properties file under SLAVE_HOSTS, start the datanode and nodemanager services on the new datanode and see it join the cluster without restarting the namenode.

Re-loading cluster.properties loaded after adding node?
1. Could anyone tell me if it is possible to re-load cluster.properties configuration file without restarting the hdp services on windows please?
2. I have added a new data node, updated the cluster.properties file on the data node. Do I need to update cluster properties on all name node and data nodes?
