We are using Trino 386, and encounter the same problem. The failure information is: ``` { "type": "java.lang.RuntimeException", "message": "org.apache.kudu.client.NonRecoverableException: Scanner 7595d00fd4cc4af0a085f256b5dc09a3 not found (it may have expired)", "cause": {...

When `KuduScanner`'s keepalive requests are not sent to tserver in time, the Scanner may be garbage-collected by tserver and will lead to this error. There is a similar issue reported...

Hi, @hashhar . I will send a PR later. You can assign this issue to me.

Hi, @konnectr . It looks like the reason for the failure is a loss in test coverage. I'll take a look at it and try to add some test cases...
