---------------------------------
Summary: Prune cached replicas from DatanodeDescriptor state on
replica invalidation
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
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.
