Subject Max number of executors per worker: fieldsGrouping or shuffleGrouping
Date Fri, 11 Dec 2015 14:16:45 GMT
Hi Everyone,

I am seeing that, if I have > 2 executors using fieldsGrouping or
shuffleGrouping--basically non-local messaging--a huge amount of time is
spent in the messaging layer.

Is anyone else seeing this?
