Attachment: HDFS-11580-HDFS-7240.009.patch
Good analysis, [~vagarychen]! And thanks for helping fix the failure test.
bq. The StorageContainerException contains an error code which I think we
should expose to caller somehow. I spent quite some time looking at how to
expose exception from callbacks (e.g. thenApply we use here) but found nothing
...
I am thinking for this, if we can just print the error log when the exception
happened during async calls.
Attach the updated patch. Mainly focus on the followings:
# Fix checkstyle warnings.
# Implement the async call for {{ReadContainer}}, this call is added recently.
# Log the error message when exception threw during async calls.
Any comments are welcomed. Thanks

> This is an umbrella JIRA that needs to support a set of APIs in Asynchronous
> form.
> For containers -- or the datanode API currently supports a call
> {{sendCommand}}. we need to build proper programming interface and support an
> async interface.
> There is also a set of SCM API that clients can call, it would be nice to
> support Async interface for those too.
