Subject [jira] [Updated] (MAPREDUCE-4581) TaskHeartbeatHandler should extends HeartbeatHandlerBase
Date Fri, 24 Aug 2012 04:38:42 GMT

     [ https://issues.apache.org/jira/browse/MAPREDUCE-4581?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Siddharth Seth updated MAPREDUCE-4581:

            Priority: Minor  (was: Major)
    Target Version/s: MR-3902
                Tags:   (was: MR-3902)
            Assignee: Tsuyoshi OZAWA

Tsuyoshi, thanks for taking this up.

The patch does not look complete. It should be removing a lot of the code from TaskHeartbeatHandler.
Other than that, 1) Two events should be going out - the Diagnostic event from the current
HeartbeatHandler is missing. 2) Needs some formatting fixes. (Formatting guidelines at http://wiki.apache.org/hadoop/HowToContribute)

> TaskHeartbeatHandler extends AbstractService currently, however, this causes code duplication
between TaskHeartbeatHandler and HeartbeatHandlerBase. TaskHeartbeatHandler should extends
HeartbeatHandlerBase to solve the problem.
