@den-crane You need to check zookeeper `version` of node `/table/replicas/your_replica/metadata_version` and version of node `/table/metadata`. Also make sense to show full content of `/table/metadata` and `/table/replicas/your_replica/metadata`.

I'll join "broken CI festival" and merge this PR.

@azat Isn't this test is terribly complex and unreliable by design? Maybe it make sense to convert to unit test? Maybe it's to remove it at all?
