Subject [jira] [Closed] (UIMA-5858) UIMA-DUCC: Agent should publish its state (Available|Unavailable) in metrics
Date Mon, 27 Aug 2018 14:44:00 GMT

     [ https://issues.apache.org/jira/browse/UIMA-5858?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Jerry Cwiklik closed UIMA-5858.
-------------------------------
    Resolution: Fixed

Added new enum NodeStatus with two states: Available, Unavailable. When agent receives stop
or quiesce request it calls NodeMetrics.disableNode() where a state changes from Available
to Unavailable.

change is state to Unavailable to let clients know that it is stopping. The RM will stop scheduling
work on a node which is in Unavailable state.
