> Key: HDFS-8646
> URL: https://issues.apache.org/jira/browse/HDFS-8646
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: caching
> Affects Versions: 2.3.0
> Reporter: Andrew Wang
> Assignee: Andrew Wang
> Fix For: 2.8.0

> Currently we remove blocks from the DD's CachedBlockLists on node failure and
> on cache report, but not on replica invalidation. This can lead to an invalid
> situation where we return a LocatedBlock with cached locations that are not
> backed by an on-disk replica.
