Subject Is executor computing time affected by network latency?
Date Thu, 22 Sep 2016 13:54:09 GMT

When I increase the network latency among spark nodes, 

I see compute time (=executor computing time in Spark Web UI) also

In the graph attached, left = latency 1ms vs right = latency 500ms.

Is there any communication between worker and driver/master even 'during'
executor computing? or any idea on this result?


Thank you very much in advance.
