Timeout Exception while fetching metadata at path /

[rohitashJain]

Below is the stack trace of the error. I tried to set logging level to debug by putting environment property. Can't infer the root cause of the error and how to circumvent it. Can someone please help? @ekoutanov

[ekoutanov]

This sounds like a broker issue. Are you able to read the contents of the topic using kafka-topic-consumer?

[Wouter86]

I may have fixed the issue in my pull request, just wait for it to be accepted, or already get my fork from my github account. Then add the parameter --kafdrop.reducedTopicInfo=true when running kafdrop and you may be good to go.

I saw the same error during a cluster rebalancing executed by CruiseControl.

Caused by: org.apache.kafka.common.errors.TimeoutException: Timeout of 60000ms expired before the position for partition __KafkaCruiseControlModelTrainingSamples-22 could be determined

Kafdrop became unusable until the rebalancing task was completed.

@Wouter86 is your RP merged with master? thanks
