- The query service port for a server (used for MSE queries) can change across server restarts. - There is currently an edge case scenario with the failure detector mechanism (See https://github.com/apache/pinot/pull/15005, https://github.com/apache/pinot/pull/8491 for background) in a scenario where there are MSE queries pre server restart that have established gRPC channels to the server host / port, and there aren't any MSE queries post server restart. Here, if an SSE query failure triggers the failure detector mechanism to mark the server as unhealthy, the server won't be marked as healthy until the retry period ends or if an MSE query is sent and a new gRPC channel is established to the server's new query service port. - This patch fixes the issue to not use stale host / port information for the failure detector's retry mechanism. -- This is an automated message from the Apache Git Service.
