Error from producer sync API "Broker: Request timed out"

[ANKUR JOHRI <er...@gmail.com>]

Hi,

There is a producer which uses librdkafka to send messages over a Kafka 
infrastructure. There is an error which occurred from sync API call. It 
gives error message "Broker: Request timed out".

To give some context of the scenario, there are two brokers - broker 2 on 
local host being the preferred replica and the leader and broker 1 on 
remote host as follower. Data is produced with required.acks = 1 so that 
producer writes to leader in sync and to follower in async. We reboot 
remote host and follower broker is not available any more and this made 
error occurred on local host where producer is writing.

There is nothing much in kafka debug logs.

Please suggest what could be going wrong or let me know if more 
information is required. Thanks for your help.

Thanks,
Ankur
