Andres de la Peña updated CASSANDRA-16959:
------------------------------------------
Description:
Both {{nodetool setstreamthroughput}} and {{nodetool
setinterdcstreamthroughput}} accept a negative throughput. The throughput value
is not immediately applied to the corresponding rate limiters. Instead, the
value is [set in the
{{Config}}|https://github.com/apache/cassandra/blob/09c89e5f5f8604301c233130dfb6e82a36ae30f3/src/java/org/apache/cassandra/service/StorageService.java#L1488]
and it's only applied to the singleton rate limiter when new sstable stream
writer are created (see
[here|https://github.com/apache/cassandra/blob/09c89e5f5f8604301c233130dfb6e82a36ae30f3/src/java/org/apache/cassandra/streaming/StreamManager.java#L66-L76]).
This could happen much later than the definition of the new throughput, and by
then the setting of the new rate in the rate limiter will fail with an
{{IllegalArgumentException}} due to the negative value.
I think we should either immediately reject negative throughputs or consider
them unlimited, as we do with zero. Also we should probably apply the new
throughput to the rate limiter immediately, since I don't see why we should
wait to start using the new throughput.
