Query error: failed to send brpc batch, error=RPC call is timed out, error_text=[E1008]Reached timeout=300000ms

I executed a query in Doris and encountered an error failed to send brpc batch, error=RPC call is timed out, error_text=[E1008]Reached timeout=300000ms， The error reading seems to have timed out, which seems to be related to RPC. I searched the community and found no relevant error issues, so I have submitted this new question

Answer

as follows:

1. Internet reasons, heartbeat needs to be solved

2. Confirm whether query_timeout is 300s, adjust query_timeout, and also consider dynamically adjusting fe's max_query_retry_time

3. Version defects, can be upgraded to the latest three-digit stable version
