-------------------------------
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).
