-----------------------------------

             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 part of property
	at javax.management.ObjectName.construct(ObjectName.java:618)
	at javax.management.ObjectName.<init>(ObjectName.java:1382)
	at org.apache.kafka.common.utils.AppInfoParser.registerAppInfo(AppInfoParser.java:60)
	at org.apache.kafka.connect.runtime.ConnectMetrics.<init>(ConnectMetrics.java:77)
	at org.apache.kafka.connect.runtime.Worker.<init>(Worker.java:88)
	at org.apache.kafka.connect.cli.ConnectDistributed.main(ConnectDistributed.java:81)
{code}

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