  <p>Hi everyone,
  I got some issues with Kafka input in talend, if there is any Kafka input component in the Talend job, some components are stuck in Starting as you saw in the picture after tExtractJSONFields_1 component, it happens to some components like tuniqrow, taggregate. I already test the job and change the input components with file delimiter input, but it not showing any problem.</p>
  <p>is there any special configuration for the Kafka input component?</p>
