            Description

            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.
