[jira] [Created] (HDDS-191) Queue SCMCommands via EventQueue in SCM

Elek, Marton created HDDS-191:
---------------------------------

             Summary: Queue SCMCommands via EventQueue in SCM
                 Key: HDDS-191
                 URL: https://issues.apache.org/jira/browse/HDDS-191
             Project: Hadoop Distributed Data Store
          Issue Type: Improvement
            Reporter: Elek, Marton
            Assignee: Elek, Marton
             Fix For: 0.2.1


As a first step towards to a ReplicationManager I propose to introduce the EventQueue to the StorageContainerManager and enable to send SCMCommands via EventQueue.

With this separation the ReplicationManager could easily send the appropriate SCMCommand (eg. CopyContainer) to the EventQueue without hard dependency to the SCMNodeManager. (And later we can introduce the CommandWatchers without modifying the ReplicationManager part)
