           Status: Resolved  (was: Patch Available)

Updated {{NEWS.TXT}} wording to state that potentially affected users must run 
repair in the base table and subsequently on the views, after [mailing list 

Committed fix as {{c67338989f17257d3be95212ca6ecb4b83009326}} to cassandra-3.0 
and merged up to cassandra-3.11 and trunk and dtest as 
{{8fa87f63dec7dd636473b620071d264893a19df8}}. Thanks for the review

> From the [dev 
> list|https://www.mail-archive.com/dev@cassandra.apache.org/msg12084.html]:
> bq. There's an optimization that when we're lucky enough that the paired view 
> replica is the same as this base replica, mutateMV doesn't use the normal 
> view-mutation-sending code (wrapViewBatchResponseHandler) and just writes the 
> mutation locally. In particular, in this case we do NOT write to the pending 
> node (unless I'm missing something). But, sometimes all replicas will be 
> paired with themselves - this can happen for example when number of nodes is 
> equal to RF, or when the base and view table have the same partition keys 
> (but different clustering keys). In this case, it seems the pending node will 
> not be written at all...
> This was a regression from CASSANDRA-13069 and the original behavior should 
> be restored.
