Íñigo Goiri commented on HDFS-15108:
------------------------------------
Thanks [~ayushtkn] for the update.
A couple minor style comments:
* I would make the invalidation into a method: {{invalidateCache(final String
nsId)}} where we would do the code you have there.
* Let's make getInetSocketAddress() static.
* In the javadoc for getInetSocketAddress() mention is the format host:port.
> RBF: MembershipNamenodeResolver should invalidate cache incase of active

> If a failover happens, {{namenodeResolver.updateActiveNamenode(nsId,
> address);}} is called, but this doesn't invalidates the cache, so as the next
> time the correct active is fetched.
