Lei (Eddy) Xu commented on HDFS-11718:
--------------------------------------
Thanks for the patch, [~manojg]. It LGTM. +1 pending for jenkins and after
addressing small nits.
* Can we use {{try-resource}} for {{FSDataOutputStream}} used in the test.
* Please add comments to the test as a reference, since this JIRA is a hot fix.
Thanks!

> This is a clone bug of HDFS-11644 to provide a quick fix while a proper fix
> is being discussed and developed. The quick fix here would be to just turn
> {{DFSStripedOutputStream#hsync()/hflush()}} as a no-op instead of throwing
> UnsupportedOperationException.
> @Override
> public void hflush() {
> throw new UnsupportedOperationException();
> }
> @Override
> public void hsync() {
> throw new UnsupportedOperationException();
> }
> For more details please refer to the comments in HDFS-11644.
