[jira] [Commented] (HBASE-22804) Provide an API to get list of
successful regions and total expected regions in Canary
[ https://issues.apache.org/jira/browse/HBASE-22804?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16901693#comment-16901693 ]
stack commented on HBASE-22804:
-------------------------------
Sounds good. Does it have to be an API or is it just a report the Canary dumps after each run in a manner parseable by other tools? Or should Canary listen on port and respond to queries replying in JSON w/ its current understanding of what is up w/ the cluster?
Should it be a query you can run against the Master instead? Could ask the Master to run Canary ops? It is always up so you could ask it for current status?
Thanks.
