Date Mon, 12 Sep 2016 21:22:20 GMT


Micah Whitacre updated CRUNCH-621:
    Attachment: CRUNCH-621.patch

Patch that should now check on each reader startup to make sure there is data to retrieve
before start looping and expect data.

> With the KafkaSource and specifically the KafkaRecordReader, if there is no data to consume
from a partition because all data fell off Kafka then we can end up in a situation where the
KafkaRecordReader will poll forever as it never gets data to reach its ending offset.
