[jira] [Created] (HDFS-5715) Use Snapshot ID to indicate the corresponding Snapshot for a FileDiff/DirectoryDiff

Jing Zhao created HDFS-5715:
-------------------------------

             Summary: Use Snapshot ID to indicate the corresponding Snapshot for a FileDiff/DirectoryDiff
                 Key: HDFS-5715
                 URL: https://issues.apache.org/jira/browse/HDFS-5715
             Project: Hadoop HDFS
          Issue Type: Sub-task
            Reporter: Jing Zhao
            Assignee: Jing Zhao


Currently FileDiff and DirectoryDiff both contain a snapshot object reference to indicate its associated snapshot. Instead, we can simply record the corresponding snapshot id there. This can simplify some logic and allow us to use a byte array to represent the snapshot feature (HDFS-5714).
