Just a quick note so no one does the same oops that I did (and also reply if this one has happened to you):
I had 2 nodes in a cluster with matching data
I removed node 2 from the cluster and manually deleted the data directory
I stopped both nodes
I started node 2 first and then node 1
Node 2 was the master and did not seem to be picking up the existing index that remained on node 1
I thought maybe if I did a create of that same index on Node 2 that it might get it to "see" the configured index on node 1
Instead Node 2 basically obliterated node 1 with a blank new index?
OOOOPS (luckily it was a dev/poc environment)
Is this even possible? Did something else happen?
