> Currently,
> {{RawLocalFileSystem.DeprecatedRawLocalFileStatus#loadPermissionInfo}} is
> implemented as forking an {{ls}} command and parsing the output. This was
> observed to be a bottleneck in YARN-3491. This issue proposes an optional
> native implementation of a {{stat}} syscall through JNI. We would maintain
> the existing code as a fallback for systems where the native code is not
> available.
