----------------------------------------------
> Perhaps this method could reasonably be added to o.a.h.hdfs.client.HdfsAdmin?
This is not an admin method. Any user could have an application using it.
> ... We might want to wait for resolution of that issue before we introduce
> this new API that we know won't work as intended.
It will work for non-HA setup. So, we should not wait for HDFS-3507. If there
is a bug in HA, it should not stop other development.
> Provide API to check HDFS operational state
