>            Reporter: Andrew Wang

> FSDataOutputStream#hsync checks if a stream implements Syncable, and if so, calls hsync.
Otherwise, it just calls flush. This is used, for instance, by YARN's FileSystemTimelineWriter.
> DFSStripedOutputStream extends DFSOutputStream, which implements Syncable. However, DFSStripedOS
throws a runtime exception when the Syncable methods are called.
> We should refactor the inheritance structure so DFSStripedOS does not implement Syncable.
