Xun REN created HADOOP-15777:
--------------------------------

             Summary: Add support of getSnapshotDiff for all the FS inherit from FileSystem
                 Key: HADOOP-15777
                 URL: https://issues.apache.org/jira/browse/HADOOP-15777
             Project: Hadoop Common
          Issue Type: New Feature
          Components: fs
    Affects Versions: 3.3.0
            Reporter: Xun REN


As proposed by [~jojochuang] in the Jira HDFS-13916, I create this Jira which depends on HADOOP-15691 in order to add support of getSnapshotDiff for all the File Systems inherit from the parent class FileSystem.

This method is used to get difference between two snapshots, which is mostly used to do DistCP with "-diff" option.
