Subject Spark driver CPU usage
Date Wed, 01 Mar 2017 12:11:18 GMT

Is there a way to control CPU usage for driver when running applications in client mode?

Currently we are observing that the driver occupies all the cores. Launching just 3 instances
of driver of WordCount sample application concurrently on the same machine brings the usage
of its 4 core CPU to 100%. Is this expected behaviour?
