[jira] [Created] (HDFS-5584) Add OOB upgrade response and client-side logic for reads

Kihwal Lee created HDFS-5584:
--------------------------------

             Summary: Add OOB upgrade response and client-side logic for reads
                 Key: HDFS-5584
                 URL: https://issues.apache.org/jira/browse/HDFS-5584
             Project: Hadoop HDFS
          Issue Type: Sub-task
            Reporter: Kihwal Lee


Similarly to HDFS-5583, readers can also benefit from the knowledge that a data node failure is caused by an upgrade restart.  Instead of permanently removing from the potential data source for the client, it could retry the node more times before declaring it dead.
