@HeartSaVioR @srdo ., The issue in assuming that `InterruptedException` is
only coming from external interruptions. Below is the actual example we noticed
when Kafka Spout`TimeoutException` was wrapped in `InterruptedException`. Users
could not identify where the exception was raised.
```
KafkaSpoutI_[39 39] [WARN] Expecting exception of class: class
java.lang.InterruptedException, but exception chain only contains:
(#<TimeoutException org.apache.kafka.common.errors.TimeoutException: Failed to
get offsets by times in 40000 ms>)```
