Peter Vary commented on HIVE-16294: ----------------------------------- There is a non public API to find out, if a directory is snapshottable or not: - DFSClient.getSnapshottableDirListing(), or - DistributedFileSystem.getSnapshottableDirListing()) IMO, here is how we should handle this: - Create a Hadoop jira for requesting a public API. - Until the API is available it is enough to check if the fs is an instance of DistributedFileSystem, and the filename is ".snapshot" - Add a comment to remove this code, when the API is available. But I would like to know how the more experienced guys think about this. What do you think about this:[~aihuaxu], [~andrew.wang]?
