Jing Zhao updated HDFS-4230:
----------------------------
Attachment: HDFS-4230.001.patch
Initial patch uploaded.
Unlike ClientProtocol#getListing and listCorruptFiles, this patch simply
returns all the current snapshottable directories, considering 1) the number of
snapshottable directories may be not very large, and 2) currently all the
snapshottable directories are stored in an unsorted list in the SnapshotManager
thus it is hard to continue the listing from the middle.
