[jira] [Created] (HDFS-12979) StandbyNode should upload FsImage to ObserverNode after checkpointing.

Konstantin Shvachko created HDFS-12979:
------------------------------------------

             Summary: StandbyNode should upload FsImage to ObserverNode after checkpointing.
                 Key: HDFS-12979
                 URL: https://issues.apache.org/jira/browse/HDFS-12979
             Project: Hadoop HDFS
          Issue Type: Sub-task
            Reporter: Konstantin Shvachko


ObserverNode does not create checkpoints. So it's fsimage file can get very old making bootstrap of ObserverNode too long. A StandbyNode should copy latest fsimage to ObserverNode(s) along with ANN.
