> Key: CASSANDRA-14801
> URL: https://issues.apache.org/jira/browse/CASSANDRA-14801
> Project: Cassandra
> Issue Type: Bug
> Components: Legacy/Coordination, Legacy/Distributed Metadata
> Reporter: Benedict Elliott Smith
> Assignee: Aleksandr Sorokoumov
> Priority: Normal
> Labels: pull-request-available
> Fix For: 4.0, 4.0-beta
>
> Time Spent: 10m
> Remaining Estimate: 0h
>
> Correctness depended upon the narrowing to a {{Set<InetAddressAndport>}},
> which we no longer do - we maintain a collection of all {{Replica}}. Our
> {{RangesAtEndpoint}} collection built by {{getPendingRanges}} can as a result
> contain the same endpoint multiple times; and our {{EndpointsForToken}}
> obtained by {{TokenMetadata.pendingEndpointsFor}} may fail to be constructed,
> resulting in cluster-wide failures for writes to the affected token ranges
> for the duration of the range movement.
