[jira] [Issue Comment Deleted] (CASSANDRA-16381) nodetool removenode error “Conflicting replica added”

---------------------------------------
Comment: was deleted
(was: [~brandon.williams] Could it be linked to the changes to {{CassandraCompressedStreamWriter}} and {{CassandraStreamWriter}} where we create a new channel instead or reusing the existing one (see https://github.com/apache/cassandra/commit/9f6fcc340d89eecc000765f6ab93e862f53a02d9)?
That change was added to prevent interruped thread from closing the backing channel but it can probably be achieved in another way.)

> When testing elassandra on C* 4.0, integration tests with ccm systematically failed on removing a node with the following error “Conflicting replica added” . [This integration test |https://github.com/strapdata/elassandra/blob/v6.8.4-strapdata/integ-test/test-cleanup-repair.sh#L289] was ok with Elassandra based on Cassandra 3.11, and there is no changes in that test. Moreover, it seems there is no cassandra-test (dtest) for removing a node (there is only one removenode test for transient replication). The topology_test.py remove a node from the CCM cluster, but it does not call nodetool removenode.
> I wonder if we have a non-tested regression here in C 4.0 ?
