I am using jdbc to connect presto,it is successfully sometimes,but sometimes it is failed with exception
Does anyone have a solution for this issue? We have ran into a similar issue too.From the log: GetTableLocations request on kudu.master.MasterService from 10.0.134.172:33350 dropped due to backpressure. The service queue is full; it has 2000 items. [suppressed 2633 similar messages]_
, it seems the request was dropped by kudu because of the backpressure. What could we do for that? Slow the speed of writing to Kudu?
