Azat Khuzhin 3e68103ac8 Fix interserver secret for Distributed over Distributed from remote() ... Right if you are executing remote() and later the query will go to the cluster with interserver secret, then you should have the same user on the nodes from that cluster, otherwise the query will fail with: DB::NetException: Connection reset by peer And on the remote node: <Debug> TCPHandler: User (initial, interserver mode): new_user (client: 172.16.1.5:40536) <Debug> TCP_INTERSERVER-Session: d29ecf7d-2c1c-44d2-8cc9-4ab08175bf05 Authentication failed with error: new_user: Authentication failed: password is incorrect, or there is no user with such name. <Error> ServerErrorHandler: Code: 516. DB::Exception: new_user: Authentication failed: password is incorrect, or there is no user with such name. (AUTHENTICATION_FAILED), Stack trace (when copying this message, always include the lines below): The problem is that remote() will not use passed to it user in any form, and instead, the initial user will be used, i.e. "cli_user" not "query_user": chc --user cli_user -q "select * from remote(node, default, some_dist_table, 'query_user')" Fix this by using the user from query for the remote(). Note, that the Distributed over Distributed in case of tables still wont work, for this you have to have the same users on all nodes in all clusters that are involved in case of interserver secret is enabled (see also test).
