[jira] [Created] (SLING-8557) KafkaMessagePoller does not recover in case of exceptions

Christian Schneider created SLING-8557:
------------------------------------------

             Summary: KafkaMessagePoller does not recover in case of exceptions
                 Key: SLING-8557
                 URL: https://issues.apache.org/jira/browse/SLING-8557
             Project: Sling
          Issue Type: Bug
          Components: Content Distribution
    Affects Versions: Content Distribution Journal Kafka 0.1.2
            Reporter: Christian Schneider
            Assignee: Christian Schneider
             Fix For: Content Distribution Journal Kafka 0.1.4


Currently  the KafkaMessagePoller simply shuts down on any exception while talking to Kafka. 

This leads to the system being in a non working state.

I propose we move the error handling inside the while (running) loop. 

The javadoc of KafkaConsumer say: "This client transparently handles the failure of Kafka brokers". 

So I would expect that we can simply log exceptions and KafkaConsumer handles the reconnect.
