Subject [jira] [Updated] (HADOOP-15562) Add Software Load Balancing support for Hadoop/Yarn Process
Date Tue, 26 Jun 2018 16:28:00 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-15562?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

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).
