Daryn Sharp created HDFS-4379: --------------------------------- Summary: DN block reports should include a sequence number Key: HDFS-4379 URL: https://issues.apache.org/jira/browse/HDFS-4379 Project: Hadoop HDFS Issue Type: Improvement Components: datanode, namenode Affects Versions: 2.0.0-alpha, 3.0.0 Reporter: Daryn Sharp
Block reports should include a monotonically increasing sequence number. If the sequence starts from zero, this will aid the NN in being able to distinguish a DN restart (seqNum == 0) versus a re-registration after network interruption (seqNum != 0). The NN may also use it to identify and skip already processed block reports. -- This message is automatically generated by JIRA.
