Subject [jira] [Created] (HIVE-9820) LLAP: Use a share-nothing scoreboard /status implementation
Date Sat, 28 Feb 2015 01:59:04 GMT
Gopal V created HIVE-9820:

             Summary: LLAP: Use a share-nothing scoreboard /status implementation
                 Key: HIVE-9820
             Project: Hive
          Issue Type: Sub-task
            Reporter: Gopal V

To prevent thread-conflicts in executor information, the Apache HTTP servers use a share-nothing
data structure known as a scoreboard.

This is read by various systems like mod_status to read out the current state of  executors
available for PHP (and similar mod_* engines).

The /status output is traditionally periodically read by the load-balancers to route requests
away from busy machines.
