Paulo Motta commented on CASSANDRA-9875:
----------------------------------------
Sorry for the delay here. Implementation looks mostly good, but I find the UI a
bit counter-intuitive, since if you want to rebuild multiple ranges from a
single or small set of sources (a typical use case IMO), you'd need to repeat a
source multiple times (one for each specified range). Unless you have a use
case in mind for this, I think a more intuitive interface would be a host
whitelist (similar to repair {{--hosts}}), and this would also make
implementation a bit simpler, since you could simply add a source filter to
RangeStreamer (avoiding the need for {{addRangesWithSources}}). This would
still allow you to specify a direct range-source mapping by running multiple
rebuild commands. WDYT?
Also, could you add a simple dtest?

> Nodetool rebuild command will rebuild all the token ranges handled by the
> endpoint. Sometimes we want to rebuild only a certain token range. We should
> add this ability to rebuild command. We should also add the ability to stream
