> [shouldDestroy|https://github.com/szetszwo/hadoop/blob/331e075115b4a35574622318b26f6d4731658d57/hadoop-hdfs-project/hadoop-hdfs/src/main/java/org/apache/hadoop/hdfs/server/namenode/INodeReference.java#L834-L845]
> method which caused the following bug.
> h3. Background:
> - When {{FileSystem.rename(src, dst)}} from a snapshottable dir (src) to a
> snapshottable dir (dst), dstSnapshotId is set to the latest snapshot at dst.
> As a result, dst is NOT in dstSnapshotId because dstSnapshotId was already
> taken before rename.
> - snapshotToBeDeleted is the snapshot id of the current operation if the
> operation is {{{}FileSystem.deleteSnapshot{}}}. Otherwise,
> snapshotToBeDeleted is set to CURRENT_STATE_ID.
> - If (snapshotToBeDeleted > dstSnapshotId), dst is in snapshotToBeDeleted.
> The shouldDestroy method returns true to continue deletion.
> - If (snapshotToBeDeleted <= dstSnapshotId), dst must not be in
> snapshotToBeDeleted. The shouldDestroy method returns false to stop deletion.
> All the above are correct for renaming within snapshottable directories.
> h3. Bug:
> - If rename(src, dst) from a snapshottable dir (src) to a non-snapshottable
> dir (dst), dstSnapshotId becomes CURRENT_STATE_ID.
> - When {{FileSystem.delete(dst)}} happens, snapshotToBeDeleted is also set
> to CURRENT_STATE_ID.
> - In this case, snapshotToBeDeleted == dstSnapshotId, the shouldDestroy
> method will return false and it incorrectly stops the deletion.
> Not that this bug may cause fsimage corruption and quota miscalculation since
> some files can be partially deleted. Fortunately, this bug won't cause data
> loss.
