[jira] [Created] (HDFS-8404) pending block replication can get stuck using older genstamp

Nathan Roberts created HDFS-8404:
------------------------------------

             Summary: pending block replication can get stuck using older genstamp
                 Key: HDFS-8404
                 URL: https://issues.apache.org/jira/browse/HDFS-8404
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: namenode
    Affects Versions: 2.7.0, 2.6.0
            Reporter: Nathan Roberts
            Assignee: Nathan Roberts


If an under-replicated block gets into the pending-replication list, but later the  genstamp of that block ends up being newer than the one originally submitted for replication, the block will fail replication until the NN is restarted. 

It will be safer if processPendingReplications()  gets up-to-date blockinfo before resubmitting replication work.
