             Summary: Kafka Scala classes should declare thrown checked exceptions to be Java friendly
                 Key: KAFKA-796
                 URL: https://issues.apache.org/jira/browse/KAFKA-796
             Project: Kafka
          Issue Type: Bug
          Components: core
            Reporter: Darren Sargent
            Priority: Minor


For example, ConsumerIterator makeNext() method calls BlockingQueue.take() which declares it throws InterruptedException. However, since makeNext() fails to redeclare this exception, Java client code will be unable to catch it -- javac will complain that InterruptedException cannot be thrown.

Workaround - in the Java client code, catch Exception then check if instanceof InterruptedException and respond accordingly. But really the Scala method should redeclare checked exceptions for Java's benefit, even though it's not required for Scala since there are no checked exceptions.

There may be other classes where this needs to be done as well.
