The ResourceManager REST APIs provide some information that we can't obtain from YarnClient <https://hadoop.apache.org/docs/r2.6.0/api/org/apache/hadoop/yarn/client/api/YarnClient.html>. For example, the http://<rm http address:port>/ws/v1/cluster/scheduler endpoint provides "AMResourceUsed" which is not provided by YarnClient.
Are there any plans to add this additional information to YarnClient in the future? Thanks, Benson
