Alex Petrov commented on CASSANDRA-9507:
----------------------------------------

Yes, I meant we should leave it out for {{2.1}}. Sorry I forgot to mention the 
version number, added now.

As regards the patch, I still can see Benjamin's comments there:

  * {{final}} keywords in {{catch}} blocks in [3.0 
patch|https://github.com/ifesdjeen/cassandra/commit/4e6a45a0ffc11a8e0589fd4b48d9d3850ed535ab#diff-71f06c193f5b5e270cf8ac695164f43aR2066]
 (btw, it merges clean to trunk) (if it was the only thing we could just fix it 
on commit)
  * exceptions thrown in {{StorageProxy::getRangeSlice}} are [still 
there|https://github.com/ifesdjeen/cassandra/blob/4e6a45a0ffc11a8e0589fd4b48d9d3850ed535ab/src/java/org/apache/cassandra/service/StorageProxy.java#L2165].
 [~blerer] has suggested to remove them since they're not thrown there. As he 
mentioned, for example, the {{UnavailableException}} is thrown in 
{{RangeCommandIterator#query}} (since it calls {{assureSufficientLiveNodes}} 
originally and bubbled up. As far as I can say, they're thrown in a different 
way/different place in {{2.2}}. 

> range metrics are not updated for timeout and unavailable in StorageProxy
