URL: https://github.com/apache/hadoop/pull/4441#issuecomment-1157792454
@ZanderXu is https://github.com/apache/hadoop/pull/4127 I have
configurations on both the router and client side. Consistency is also
guaranteed because the router always does an msync.
The reason for the client side configuration is for latency sensitive
clients that just want one call between the router and the namenodes.
