How to Suppress Connection refused errors , when multiple broker configured and few brokers are not reachable

[kannanraju1979]

Hi All,
I have a configured kafka bootstrap brokers as a CSV format. ip1:9093, ip2:9093, ip3:9093.

What I observed is If any one of the bootstrap server is not reachable(But other are reachable and able to connect), I keep getting continuously errors/Failure messages flooded for that un-reachable ip:port ..
in the client logs..

Sample logs..

Is there any setting to suppress this log message?.. In my test setup at any point of time only 1 bootstrap server is active.. Other will be down..

Any help or suggestion is appreciated.

I m using a C library for kafka client side.
Thanks
