[~kiranvelumuri], I got it from `TestCrudCompactorOnTez`, probably since
`org.apache.hadoop.hive.kafka.KafkaDagCredentialSupplier` isn’t on the
`hive-unit` classpath.
It might be better to refactor so that the DagCredential class is loaded lazily
on demand and drop the error (maybe change to DEBUG or TRACE)
