qzsee opened a new issue, #11282:
URL: https://github.com/apache/doris/issues/11282

   ### Search before asking
   
   - [X] I had searched in the [issues](https://github.com/apache/incubator-doris/issues?q=is%3Aissue) and found no similar issues.
   
   
   ### Description
   
   When the query is executed, the generated execution fragment is sent to the BE node. At this time, the BE node breakdown, and RPC failed will appear(`rpc failed,host:xxx` `send fragment timeout. backend id:xxx,host:xxx`). although the heartbeat of the BE node is normal. RPC failed directly causes the query failure.
   
   Although there is a blacklist mechanism, this does not necessarily solve the problem, because BE nodes with normal heartbeat will not always work
   
   In my opinion, this single point of failure should be fault-tolerant for distributed systems.
