> JHS UserLogDir scan algorithm sometime could skip directory with update in
> CloudFS (Azure FileSystem, S3, etc.)

>
> In our cluster based on a Cloud FileSystem, we notice JHS sometimes could
> skip directory with .jhist file in scanning.
> The behavior is like:
> First round scan, doesn't found .jhist file:
> {noformat}
> 16/04/13 11:14:34 DEBUG azure.NativeAzureFileSystem: Found path as a
> directory with 6 files in it.
> 16/04/13 11:14:34 DEBUG hs.HistoryFileManager: Found 0 files
> ...
> {noformat}
> Then, we see "Scan not needed of ..." for the same directory every 3 minutes
> until application failed as timeout.
> From our analysis, we found the root cause is: most of Cloud File System
> (Azure FS, S3, etc.) is truncating file/directory modification time to
> seconds instead of milliseconds - which could due to limit of http protocol
> (from discussion at:
> https://forums.aws.amazon.com/thread.jspa?messageID=476615).
> So if the time sequence is happen to be: latest non .jhist file modification
> on directory happens at T1, directory scanning happens at T2, .jhist file
> added to directory at T3. If we have {{T1< T2 < T3}} and T1 is equal to T3
> after truncating to seconds, this issue could appear.
