I am trying to load segments which adds up to the size of 1 TB. I am running 4 r3.8xlarge instances for the historical node. In coordinator UI it shows like this.
When I am trying to do simple queries like group by on single column it is getting timed out. In coordinator logs, we can see log related to load segment
2017-05-17T05:09:49,522 INFO [Master-PeonExec–0] io.druid.server.coordinator.LoadQueuePeon - Server[/druid/prod/loadQueue/x.x.x.x:8083] processing segment[Test_Feed_2017-03-07T20:22:00.000Z_2017-03-07T20:23:00.000Z_2017-05-11T02:49:21.465Z]
Do I need to add more historical nodes? I have created segments for a minute which are the size of approx 30-40MB.
