Just to clarify one point - the iptables were running on 2nd DataNode which I didn't check, as I was sure the problem is in the NameNode/DataNode, and on NameNode/DataNode. But I can't understand what and when launched them, as I checked multiple times and nothing was running before. Moreover, they were disabled on start-up, so they shouldn't come up in the first place.
