Description

When running new consumer with SSL, debug logs show these exceptions every time:

[2015-10-19 20:57:43,389] DEBUG Fetch failed (org.apache.kafka.clients.consumer.internals.Fetcher)
org.apache.kafka.clients.consumer.internals.SendFailedException

The exception occurs because send is queued before SSL handshake is complete. I am not sure if the exception is harmless, but it will be good to avoid the exception either way since it feels like an exception that exists to handle edge cases like buffer overflow rather than something in a normal code path.
