Chao Sun commented on HDFS-13749:
---------------------------------
Thanks [~xkrogen] and [~shv].
Good to know that connections can be re-used. Yes, I think it's better to go
with {{NameNodeProxies#createNonHAProxy()}} and add a new clause for
{{HAServiceProtocol}}. I haven't checked HDFS-13779 - will build this on top
of it.

> In HDFS-12976 currently we discover NameNode state by calling
> {{reportBadBlocks}} as a temporary solution. Here, we'll properly implement
> this by using {{HAServiceProtocol#getServiceStatus}}.
