This jira proposes to move that code to a > new class named {{ReplicationManager}} for cleaner code logic, shorter source > files, and easier lock separating work in future. > The {{ReplicationManager}} is a package local class, providing > {{BlockManager}} with methods that accesses its internal data structures of > replication queue. Meanwhile, the class maintains the lifecycle of > {{replicationThread}} and {{replicationQueuesInitializer}} daemon. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
