> Currently, there are two ways to achieve KMS HA.
> The first one, and the only documented one, is running multiple KMS instances
> behind a load balancer.
> https://hadoop.apache.org/docs/stable/hadoop-kms/index.html
> The other way, is make use of LoadBalancingKMSClientProvider which is added
> in HADOOP-11620. However the usage is undocumented.
> I think we should update the KMS document to introduce
> LoadBalancingKMSClientProvider, provide examples, and also update
> kms-site.xml to explain it.
