Jeff Jirsa commented on CASSANDRA-10708:
----------------------------------------
Sorry about that. Force pushed all 3 branches with check for null before adding
to the map of descriptors.
> Add forceUserDefinedCleanup to allow more flexible cleanup for operators

> Key: CASSANDRA-10708
> URL: https://issues.apache.org/jira/browse/CASSANDRA-10708
> Project: Cassandra
> Issue Type: Improvement
> Components: Tools
> Reporter: Jeff Jirsa

>
> {{nodetool cleanup}} currently executes in parallel on all sstables in a
> table. No source sstables are GCd until the parallel operation completes. In
> certain scenarios, this is nonideal (it has both memory and disk usage
> implications for operators who try to run the operation on larger tables).
> Adding {{forceUserDefinedCleanup}} puts cleanup operations closer to parity
> with compaction {{forceUserDefinedCompaction}} for the rare cases where
> operators need to do something slightly different than the traditional
> cleanup.
