log in get record and offset from Kafka
URL: https://github.com/apache/spark/pull/26632#issuecomment-558106785
 
 
   I think the issue is more than just logging something here and there. 
[KAFKA-1894](https://issues.apache.org/jira/browse/KAFKA-1894) is a serious 
issue which was fixed in Kafka 2.0.0. Since the change only effects the 
consumer and Spark has already this version `maybe` Spark doesn't need to run 
consumers on `UninterruptibleThread`.
   
   * Micro-batch processing has still this feature which can be removed after 
it has been double checked that the mentioned Kafka jira solved all the APIs 
which are used by Spark.
   * Continuous processing I guess not considered 
[KAFKA-1894](https://issues.apache.org/jira/browse/KAFKA-1894)
   
   So my point is first we must understand on what APIs 
[KAFKA-1894](https://issues.apache.org/jira/browse/KAFKA-1894) provided 
solution and then I see 2 options:
   * All the APIs which used by Spark fixed => `UninterruptibleThread` can be 
removed.
   * NOT all the APIs which used by Spark fixed => Continuous processing must 
use it
