Hey all,  
I am implementing a backup and restore process on our clusters with hdfs and i was wandering what happens when a new node joins the cluster or an old one is replaced with a new machine?  
Because at first, we need to install the hdfs plugin and restart the service on all nodes before we register the snapshot repository. So what happens when a new node joins without the plugin installed? Will the next attempt of creating a snapshot fail?

Yes it will, unless you set the ignore unavailable flag.
