[GitHub] [druid] sirianni opened a new issue #10028: Consistent HTTP 504 error responses for query timeouts

sirianni opened a new issue #10028:
URL: https://github.com/apache/druid/issues/10028


   ### Affected Version
   `0.17.0`
   
   ### Description
   
   #### Expected Behavior
   When a Druid query hits the `timeout` set in the query context, a consistent error response should be returned, ideally with an `HTTP 504` error code.
   
   #### Actual Behavior
   In practice, we see several different responses returned for this scenario, all with an `HTTP 500` error code.  This makes it difficult to detect and handle the error in client code.
   
   ```json
   {
     "error": "Unknown exception",
     "errorMessage": "Sequence iterator timed out waiting for data",
     "errorClass": "org.apache.druid.java.util.common.RE",
     "host": null
   }
   ```
   
   ```json
   {
     "error": "Unknown exception",
     "errorMessage": "Query[3e115fa5-abf6-4496-8632-2b0196300e7c] url[http://druid-prod-middle-manager-38.druid-prod-middle-manager.druid-prod.svc.cluster.local:8100/druid/v2/] timed out.",
     "errorClass": "org.apache.druid.java.util.common.RE",
     "host": null
   }
   ```
   
   ```json
   {
     "error": "Unknown exception",
     "errorMessage": "Query[8245c738-799b-4901-8d00-6a64e1e55b81] url[http://druid-prod-historical-23.druid-prod-historical.druid-prod.svc.cluster.local:8083/druid/v2/] timed out.",
     "errorClass": "org.apache.druid.java.util.common.RE",
     "host": null
   }
   ```
   
   ```json
   {
     "error": "Query timeout",
     "errorMessage": "Timeout waiting for task.",
     "errorClass": "java.util.concurrent.TimeoutException",
     "host": "druid-prod-historical-0.druid-prod-historical.druid-prod.svc.cluster.local:8083"
   }
   ```
