what does it mean to do GET /_cluster/health? with local = true passed as query parameter
ElasticSearch documentation says
If true returns the local node information and does not provide the state from master node. Default: false.
Does this mean that setting local to true will give a cluster health as seen from local node ? or does it tell about the state of the indices/shards that are present in local node as opposed to masternode. If latter holds true, what does the status green|red|yellow status indicate since we are talking about only 1 node and not the master
In what scenarios setting local to true and setting local to false will give different results?
