-------------------------------------

[~tzulitai] I just watch FlinkKinesisConsumer which under the package of {code}org.apache.flink.streaming.connectors.kinesis{code} in the module flink-connector-kinesis.  And the flink-connector-kinesis is under the module of flink-connectors in which pom.xml dont contains the {code}flink-connector-kinesis{code}. I would think we should add the module {code} flink-connector-kinesis {code} in flink-connectors pom.xml and then return to this issue. How do you think of this ?

> The {{shutdownFetcher}} method of {{KinesisDataFetcher}} is not protected against the condition when the source was closed before it started running. Both {{mainThread}} and {{shardConsumersExecutor}} should have null checks.
