Subject [jira] [Commented] (HBASE-15511) ClusterStatus should be able to return responses by scope
Date Thu, 18 Aug 2016 17:16:20 GMT

    [ https://issues.apache.org/jira/browse/HBASE-15511?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15426834#comment-15426834
] 

Reid Chan commented on HBASE-15511:
-----------------------------------

A client can retrieve desired information of ClusterStatus by providing a scope named ClusterInfo.

If ClusterInfo is not provided, all information will be retrieved as original version.

It can be applied to cluster wide, but only after being reviewed and with permissions.

> The current ClusterStatus response returns too much information about the load per region
and replication cluster wide. Sometimes that response can be quite large (10s or 100s of MBs)
and methods like getServerSize() or getRegionsCount() don't really need the full response.
One possibility is to provide a scope (or filter) for the ClusterStatus requests to limit
the response back to the client.
