> 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-beta5, 4.0, 4.0-beta
>
> Time Spent: 10m
> Remaining Estimate: 0h
>
> 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.
