Subject Re: CPU Usage on distributed queries
Date Tue, 04 Apr 2017 06:49:34 GMT

Do the two nodes with the highest load reside on the same physical machine?
If that is so and the queries were run from that machine, then I could
assume that the cpu load is due to the reduce step being held there.

Kind regards,

How was Ignite nodes and physical machines mapped?
Where Ignite nodes more there is CPU utilization greater, isn't it?

Where were SQL query generated (on one of a srever node or other)?

I think, CPU utilization shuold be same over of nodes, because SQL executed
as Map Reduce task.
