Description

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.
