Íñigo Goiri updated HADOOP-15562:
---------------------------------
Description:
Software Load Balancers usually rely on the return code of an endpoint to
determine if a service is available to serve requests.
Currently, one can use interfaces like JMX to check the status of the service.
However, there is a need to do the mapping between the JMX values and the state
of the service.
We should provide an interface (potentially REST) to check for particular JMX
(or a new ones) values and report a particular HTTP code (e.g., 200).
