aravi5 opened a new pull request #1463: DRILL-6625: Intermittent failures in Kafka unit tests
URL: https://github.com/apache/drill/pull/1463
 
 
   ### Fix producer errors
   - Increase the value of `ProducerConfig.REQUEST_TIMEOUT_MS_CONFIG` to accomadate slower
systems.
   - Increase the value of producer `ProducerConfig.RETRIES_CONFIG` to 3 (from 0).
   - Prevent producer to send duplicate messages due to retries by setting `ProducerConfig.ENABLE_IDEMPOTENCE_CONFIG`
to `true`.
   
   ### Fix consumer errors
   - Increase `ExecConstants.KAFKA_POLL_TIMEOUT` (from 200 ms).
   
   ### Stabilize KafkaFilterPushdownTest
   - Catch the issue with setup early by checking if expected number of records exist before
running tests in `KafkaFilterPushdownTest` class.
   
   Please refer to [DRILL-6625](https://issues.apache.org/jira/browse/DRILL-6625) for more
details about the fix.
