> Unsafe to run nodetool cleanup during bootstrap or decommission
> ---------------------------------------------------------------
>
> Key: CASSANDRA-16418
> URL: https://issues.apache.org/jira/browse/CASSANDRA-16418
> Project: Cassandra
> Issue Type: Bug
> Components: Consistency/Bootstrap and Decommission
> Reporter: James Baker
> Assignee: Lindsey Zurovchak
> Priority: Normal
> Fix For: 4.0.x
>
> Time Spent: 1h 20m
> Remaining Estimate: 0h
>
> What we expected: Running a cleanup is a safe operation; the result of
> running a query after a cleanup should be the same as the result of running a
> query before a cleanup.
> What actually happened: We ran a cleanup during a decommission. All the
> streamed data was silently deleted, the bootstrap did not fail, the cluster's
> data after the decommission was very different to the state before.
> Why: Cleanups do not take into account pending ranges and so the cleanup
> thought that all the data that had just been streamed was redundant and so
> deleted it. We think that this is symmetric with bootstraps, though have not
> verified.
> Not sure if this is technically a bug but it was very surprising (and
> seemingly undocumented) behaviour.
