             Summary: Remove shard list querying from Kinesis consumer 
constructor
                 Key: FLINK-4020
                 URL: https://issues.apache.org/jira/browse/FLINK-4020
             Project: Flink
          Issue Type: Sub-task
          Components: Streaming Connectors
            Reporter: Tzu-Li (Gordon) Tai


Currently FlinkKinesisConsumer is querying for the whole list of shards in the 
constructor, forcing the client to be able to access Kinesis as well. This is 
also a drawback for handling Kinesis-side resharding, since we'd want all shard 
listing / shard-to-task assigning / shard end (result of resharding) handling 
logic to be capable of being independently done within task life cycle methods, 
with defined and definite results.
