-----------------------------------
Summary: Kafka Connect: Unsanitized workerID causes exception
during startup
Key: KAFKA-6008
URL: https://issues.apache.org/jira/browse/KAFKA-6008
Project: Kafka
Issue Type: Bug
Components: KafkaConnect
Affects Versions: 1.0.0
Environment: MacOS, Java 1.8.0_77-b03
Reporter: Jakub Scholz
Fix For: 1.0.0
When KAfka Connect starts, it seems to use unsanitized workerId for creating
Metrics. As a result it throws following exception:
{code}
[2017-10-04 13:16:08,886] WARN Error registering AppInfo mbean
(org.apache.kafka.common.utils.AppInfoParser:66)
javax.management.MalformedObjectNameException: Invalid character ':' in value

{code}
It looks like in my case the generated workerId is <IP adderess>:<port>. The
workerId should be sanitized before creating the metric.
