Ekaterina Dimitrova updated CASSANDRA-16411: -------------------------------------------- Reviewers: Andres de la Peña, Ekaterina Dimitrova, Tomasz Lasica (was: Andres de la Peña, Ekaterina Dimitrova) > Fix topology corruption on joining nodes without DC in dtests > ------------------------------------------------------------- > > Key: CASSANDRA-16411 > URL: https://issues.apache.org/jira/browse/CASSANDRA-16411 > Project: Cassandra > Issue Type: Bug > Components: Test/dtest/python > Reporter: Berenguer Blasi > Assignee: Berenguer Blasi > Priority: Normal > Fix For: 4.0-beta > > > Dtests with multi-dc setups don't update the topology properties file of a > newly joining node without dc post cluster creation. > The new node will join dc1 but it's snitch will report the default snitch > config as it doesn't get updated == dc1 == all nodes are in dc1 == there are > no other dcs. That leads to bootstrap, token, startup,... problems. Let's see > an example: > - populate [1, 1, 1] > - Node1 sees: dc1/ip1, dc2/ip2 and dc3/ip3 > - Node2 sees: dc1/ip1, dc2/ip2 and dc3/ip3 > - Node3 sees: dc1/ip1, dc2/ip2 and dc3/ip3 > - Add a new Node4 > - Node4 sees: dc1/ip1+ip2+ip3+ip4 > All multi-dc dtests that add a node after cluster creation suffer this > problem. > Solution: When a new node is added without specifying a dc in dtests check > for existing dcs. If there are any force to specify one to update the > topology file. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: commits-unsubscr...@cassandra.apache.org For additional commands, e-mail: commits-h...@cassandra.apache.org
