----------------------------------------
Summary: LoadBalancingKMSClientProvider should be documented
Key: HADOOP-13190
URL: https://issues.apache.org/jira/browse/HADOOP-13190
Project: Hadoop Common
Issue Type: Improvement
Components: documentation, kms
Affects Versions: 2.7.0
Reporter: Wei-Chiu Chuang
Assignee: Wei-Chiu Chuang
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.
