Subject [jira] [Created] (HDFS-1974) HA: Introduce active and standby states to the namenode

HA: Introduce active and standby states to the namenode
-------------------------------------------------------

                 Key: HDFS-1974
                 URL: https://issues.apache.org/jira/browse/HDFS-1974
             Project: Hadoop HDFS
          Issue Type: Sub-task
          Components: name-node
         Environment: Currently namenode supports active, secondary and backup roles. To support
namenode high availability, active and standby states are needed. Note that this is different
from the existing notion of namenode role, where a namenode cannot transition from one role
to the other.
