-----------------------------------------
bq. In any case, I think this is worth committing.
Agree.
bq. Actually I would switch the null check by hasKeyProviderUri().
I don't think {{FSserverDefaults}} has {{hasKeyProviderUri}} method.
bq. Note that the reverse convert does actually check fs.hasKeyProviderUri().
Reverse is an object FSserverDefaultsProto, thats why it has
{{hasKeyProviderUri}} method.
We can add {{hasKeyProviderUri}} method in {{FSserverDefaults}} and do null
check in that method.
> NPE for FsServerDefaults.getKeyProviderUri() for clientProtocol communication
> between 2.7 and 3.2
