Byron Ruth created KAFKA-3417: --------------------------------- Summary: Invalid characters in config not be caught early enough Key: KAFKA-3417 URL: https://issues.apache.org/jira/browse/KAFKA-3417 Project: Kafka Issue Type: Bug Components: config Affects Versions: 0.9.0.1 Reporter: Byron Ruth Priority: Minor
I ran into an error using a {{client.id}} with invalid characters (per the [config validator|https://github.com/apache/kafka/blob/trunk/core/src/main/scala/kafka/common/Config.scala#L25-L35]). I was able to get that exact error using the {{kafka-console-consumer}} script, presumably because I supplied a consumer properties file and it validated prior to hitting the server. However, when I use a client library (sarama for Go in this case), an error in the metrics subsystem is thrown [here|https://github.com/apache/kafka/blob/977ebbe9bafb6c1a6e1be69620f745712118fe80/clients/src/main/java/org/apache/kafka/common/metrics/Metrics.java#L380]. Assuming the cause os related to the invalid characters, when the request header is decoded, the {{clientId}} should be validated prior to being used? -- This message was sent by Atlassian JIRA (v6.3.4#6332)
