[jira] [Created] (HDFS-12607) Even one dead datanode with PROVIDED storage results in ProvidedStorageInfo being marked as FAILED

Virajith Jalaparti created HDFS-12607:
-----------------------------------------

             Summary: Even one dead datanode with PROVIDED storage results in ProvidedStorageInfo being marked as FAILED
                 Key: HDFS-12607
                 URL: https://issues.apache.org/jira/browse/HDFS-12607
             Project: Hadoop HDFS
          Issue Type: Sub-task
            Reporter: Virajith Jalaparti
            Assignee: Virajith Jalaparti


When a DN configured with PROVIDED storage is marked as dead by the NN, the state of {{providedStorageInfo}} in {{ProvidedStorageMap}} is set to FAILED, and never becomes NORMAL. The state should change to FAILED only if all datanodes with PROVIDED storage are dead, and should be restored back to NORMAL when a Datanode to NORMAL DatanodeStorage reports in.
