-------------------------------
Summary: For an INodeDirectoryWithSnapshot, use
INode#isInLatestSnapshot() to check if the added/removed child should be
recorded in snapshot diff
Key: HDFS-4806
URL: https://issues.apache.org/jira/browse/HDFS-4806
Project: Hadoop HDFS
Issue Type: Sub-task
Reporter: Jing Zhao
Assignee: Jing Zhao
Before supporting rename with snapshots, when adding/remove a child inode
to/from a directory, if the directory is already an INodeDirectoryWithSnapshot,
we can directly record the change in the corresponding snapshot diff.
After support rename with snapshots, an INodeDirectoryWithSnapshot may be a
renamed node, thus we should use INode#isInLatestSnapshot() to check if we
should record the change in snapshots.
