David Capwell commented on CASSANDRA-15935:
-------------------------------------------
Left feedback in PR; main comments were
* upgrade tests are broken
* (not a blocker) methods that use [calls|runs]OnInstance rather than their
nodetool versions
* StorageService#waitForSchema looks to be used wrong in src/java and causes
waits far longer than expected
* refactor joinTokenRing rather than fork (not a blocker, but makes the util
harder to use as it behaves differently and less likely to be maintained)
* gossip helper removeFromRing assert fails with all input
* should we provide ApplicationState.NET_VERSION rather than updating messaging
service version on all gossip mock events
> Improve machinery for testing consistency in presence of range movements

> Project: Cassandra
> Issue Type: Improvement
> Components: Test/dtest/java
> Reporter: Alex Petrov
> Assignee: Alex Petrov
> Priority: Normal
>
> Currently, we can test range movements only by adding and bootstrapping a new
> node. This is both inefficient and insufficient for large-scale tests. We
> need a possibility to dynamically change ring ownership over the lifetime of
> cluster, with a flexibility to changing gossip status of the node from
> perspective of other participants, adding and removing nodes from other
> nodes' views on demand.
