[jira] [Created] (HDDS-3988) running DN can distinguish SCMCommand from stale leader

Glen Geng created HDDS-3988:
-------------------------------

             Summary: running DN can distinguish SCMCommand from stale leader
                 Key: HDDS-3988
                 URL: https://issues.apache.org/jira/browse/HDDS-3988
             Project: Hadoop Distributed Data Store
          Issue Type: Sub-task
          Components: SCM
            Reporter: Glen Geng
            Assignee: Glen Geng


Due to consistency concern, SCM needs to applyTransaction to RaftLog before it writes to local database and in memory maps. Need refactor the current codes to put this part to Ratis.

Ratis will write to DB on behalf of SCM.
