      Description

      Currently both FSNamesystem and FSDirectory record edit logs. This design requires both FSNamesystem and FSDirectory to be tightly coupled together to implement a durable namespace.

      This jira proposes to separate the responsibility of implementing the namespace and providing durability with edit logs. Specifically, FSDirectory implements the namespace (which should have no edit log operations), and FSNamesystem implement durability by recording the edit logs.
