Few days ago I added a new node to my ES Cluster.
And after that all my shards start to locate only on this new node!
Please gyus, give me some advice where I need to look?
New node has ES 1.7.1 instead 1.5 in the cluster.
https://github.com/elastic/elasticsearch/issues/7363 here it's said that I need one version everywhere? Is that true?
