> On decommission of a node in a cluster with materialized views, it is possible for the decommissioning node to begin streaming sstables for an MV base table before the receiving node is aware of the leaving status.
> The materialized view base/view replica pairing checks pending endpoints to handle the case when an sstable is received from a leaving node; without the leaving message, this check breaks and an exception is thrown. The streamed sstable is never applied.
> Logs from a decommissioning node and a node receiving such a stream are attached.
