             Summary: Enable standby namenode to tail edits from journal service
                 Key: HDFS-3425
                 URL: https://issues.apache.org/jira/browse/HDFS-3425
             Project: Hadoop HDFS
          Issue Type: Sub-task
          Components: ha, name-node
            Reporter: Brandon Li
            Assignee: Brandon Li


In an HA cluster with the journal service configured, namenode should get edit logs from journal
service instead of from local or shared storage directories.  

As one of the first steps towards this goal, this JIRA is to enable standby namenode to tail
edits from journal services.
