I notice a strange behavior on the ES cluster today. Our developers attach 5 client nodes on our 5 nodes (all have data) ES cluster. While client nodes were operetional i remove a data node from the cluster to test the overhead. When cluster got green our developers stopped all the client nodes and our ES cluster crushed. We manage to recover it with a full restart. You may see the error below, somehow all nodes lost each-other. Any idea why that may happen? Thank you!
