[jira] [Created] (YUNIKORN-1493) update gang documentation to recommend FIFO

Wilfred Spiegelenburg created YUNIKORN-1493:
-----------------------------------------------

             Summary: update gang documentation to recommend FIFO
                 Key: YUNIKORN-1493
                 URL: https://issues.apache.org/jira/browse/YUNIKORN-1493
             Project: Apache YuniKorn
          Issue Type: Improvement
          Components: documentation
            Reporter: Wilfred Spiegelenburg


In the current gang scheduling documentation we show FIFO or StateAware as [prerequisite for the app sorting policy|https://yunikorn.apache.org/docs/user_guide/gang_scheduling/#prerequisite].

We should not recommend StateAware as a failing driver or a long initialisation period for a driver could slow down the processing. The StateAware timeout will  slow down processing to just one application per timeout. This in effect will overrule the gang reservation.

So you should either use FIFO with gang or StateAware without gang scheduling.
