It is useful to be able to delay state recovery until enough data nodes have joined the cluster, since this gives the shard allocator a decent opportunity to re-use as much existing data as possible. However we also have the option to delay state recovery until a certain number of master-eligible nodes have joined, and this seems unnecessary: we require a majority of master-eligible nodes for state recovery, but there is no advantage in waiting for more.
We should deprecate the following settings in 7.x and remove them in 8.0:
gateway.expected_nodesgateway.expected_master_nodesgateway.recover_after_nodesgateway.recover_after_master_nodes
