like resolving network names
Antony Stubbs created KAFKA-6268:
------------------------------------
Summary: Tools should now swallow exceptions like resolving network names
Key: KAFKA-6268
URL: https://issues.apache.org/jira/browse/KAFKA-6268
Project: Kafka
Issue Type: Bug
Components: core
Affects Versions: 0.11.0.1
Reporter: Antony Stubbs
The cli consumer client shows nothing when it can't resolve a domain. This and other errors like it should be shown to the user by default. You have to turn on DEBUG level logging in the tools log4j to find there is an error.
