-------------------------------------

             Summary: Move from randomly generated block ID to sequentially 
generated block ID
                 Key: HDFS-4645
                 URL: https://issues.apache.org/jira/browse/HDFS-4645
             Project: Hadoop HDFS
          Issue Type: Improvement
          Components: namenode
    Affects Versions: 3.0.0
            Reporter: Suresh Srinivas
            Assignee: Suresh Srinivas


Currently block IDs are randomly generated. This means there is no pattern to 
block ID generation and no guarantees such as uniqueness of block ID for the 
life time of the system can be made. I propose using SequentialNumber for block 
ID generation.
