[jira] [Resolved] (SLIDER-164) Publishing connection info for active master (e.g. HBase Active Master)

["Sumit Mohanty (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/SLIDER-164?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Sumit Mohanty resolved SLIDER-164.
----------------------------------

    Resolution: Not a Problem

Slider does not need to publish the information for active master. HBase clients can find it out from ZK. HBase Masters can publish individual host:port that can be used by any other client to find out which one is active.

> Some applications, such as HBase, may have multiple masters with one active at any given point. When such applications register the applied configuration or the access URL for UI/JMX etc. then the url registered or the ports advertised should belong to the active master.
> Slider should support a way to have the application indicate which master is active and what information must be registered by the active master. Related effort is to refresh the registry when failover occurs.
