[jira] [Created] (FLINK-32274) kafka class could not be found while using appliction mode.

Spongebob created FLINK-32274:
---------------------------------

             Summary: kafka class could not be found while using appliction mode.
                 Key: FLINK-32274
                 URL: https://issues.apache.org/jira/browse/FLINK-32274
             Project: Flink
          Issue Type: Bug
          Components: Client / Job Submission
    Affects Versions: 1.14.5
            Reporter: Spongebob


While using yarn-application mode to submit my app, it would throw an exception: `org.apache.kafka.common.config.ConfigException: Invalid value org.apache.kafka.common.serialization.StringDeserializer for configuration key.deserializer: Class org.apache.kafka.common.serialization.StringDeserializer could not be found.` I had defined KafkaProducer variation in my client code. And I think the kafka-clients dependency was already uploaded while submitting the app.

But I found it is ok in per-job mode.
