[jira] [Created] (HDFS-10842) Prevent IncrementalBlockReport processing before the first FullBlockReport has been received

Kuhu Shukla created HDFS-10842:
----------------------------------

             Summary: Prevent IncrementalBlockReport processing before the first FullBlockReport has been received
                 Key: HDFS-10842
                 URL: https://issues.apache.org/jira/browse/HDFS-10842
             Project: Hadoop HDFS
          Issue Type: Bug
            Reporter: Kuhu Shukla
            Assignee: Kuhu Shukla


In a scenario where a Datanode does not send a fullBlockReport, incremental block reports can cause the NN to make error in judgement about what blocks are on a given DN. One solution is to not process the blocks unless we have received the first full block report.
