Siyao Meng commented on HDFS-13879:
-----------------------------------
Offline discussion with [~jojochuang] concludes that we should add
getSnapshottableDirListing() as well since DistributedFileSystem has it.
BTW WebHDFS API has a different naming for it (getSnapshottableDirectoryList vs
getSnapshottableDirListing), might rename and deprecate the WebHDFS API name in
the future.
> FileSystem: Add allowSnapshot, disallowSnapshot, getSnapshotDiffReport and
> getSnapshottableDirListing

> Key: HDFS-13879
> URL: https://issues.apache.org/jira/browse/HDFS-13879
> Project: Hadoop HDFS
> Issue Type: Improvement
> Affects Versions: 3.1.1
> Reporter: Siyao Meng
> Priority: Major
>
> I wonder whether we should add allowSnapshot() and disallowSnapshot() to
> FileSystem abstract class.
> I think we should because createSnapshot(), renameSnapshot() and
> deleteSnapshot() are already part of it.
> Any reason why we don't want to do this?
> Thanks!
