Should new indexes be created before the cluster has balanced the new node could end up with a disproportionate amount of new shards. In a heavily loaded cluster this could cause stability issues.   It would be preferable to have a setting that would allow the node to participate in rebalancing while not being allocated new shards. \r\n"}}
