Everyone keeps stating how Elasticsearch is smart and knows to reallocate when a node is down.
But i cant seem to find the conditions for which Elastic determine when the node is down.
If i have a connection hiccup, will elastic start reallocating through my network? and when the node returns, elastic might see it as a "new" node and allocate it new data?
Is there a way to change those conditions?
Can I decide that if a certain machine is down, dont reallocate and state the cluster health as red?
Thanks in advance!
