> In HDFS-9794, it has solved problem of that stream thread leak if failure 
> happens when closing the striped outputstream. And in {{DFSOutputStream}}, it 
> also exists the same problem in {{DFSOutputStream#closeImpl}}. If failures 
> happen when flushing data blocks, the streamer threads will also not be 
> closed.
