Suresh Srinivas created HDFS-4645: ------------------------------------- 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. -- This message is automatically generated by JIRA.
