-------------------------------------
Summary: Need way to catch auth issues in poll method
Key: KAFKA-10840
URL: https://issues.apache.org/jira/browse/KAFKA-10840
Project: Kafka
Issue Type: Improvement
Reporter: Devin G. Bost
We recently implemented SSL authentication at our company, and when certs
expire, the Kafka client poll method silently fails without throwing any kind
of exception. This is a problem because the data flow could stop at any time
(due to certificate expiration) without us being able to handle it. The auth
issue shows up in Kafka broker logs, but we don't see any indication on the
client-side that there was an auth issue. As a consequence, the auth failure
happens 10 times a second forever.
We need a way to know on the client-side if an auth issue is blocking the
connection to Kafka so we can handle the exception and refresh the certs
(keystore/truststore) when the certs expire.
