             Summary: Move invalidate blocks to ReplicationManager
                 Key: HDFS-9506
                 URL: https://issues.apache.org/jira/browse/HDFS-9506
             Project: Hadoop HDFS
          Issue Type: Sub-task
          Components: namenode
            Reporter: Mingliang Liu
            Assignee: Mingliang Liu


The [HDFS-9442] moves basic replication mechanism from {{BlockManager}} to 
newly added {{ReplicationManager}}. After that we can move more replication 
related logic to {{ReplicationManager}} as well, e.g. _invalidate blocks_ and 
_corrupt replicas_. The goal is, again, cleaner code logic, well-organized 
source files, and easier lock separating work in future.

This jira is to track the effort of moving invalidate blocks to 
{{ReplicationManager}}.
