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

             Summary: Kafka 0.8 connector's Periodic Offset Committer should synchronize on
checkpoint lock
                 Key: FLINK-4753
                 URL: https://issues.apache.org/jira/browse/FLINK-4753
             Project: Flink
          Issue Type: Bug
          Components: Kafka Connector
            Reporter: Tzu-Li (Gordon) Tai
            Assignee: Tzu-Li (Gordon) Tai
             Fix For: 1.2.0


The {{PeriodicOffsetCommitter}} doesn't synchronize on the checkpoint lock when creating a
copy of the partition offsets in the current state.

I propose to pass the checkpoint lock into{{PeriodicOffsetCommitter}}, and  let {{PeriodicOffsetCommitter}}
use {{Kafka08Fetcher#snapshotCurrentState()}} to make the current state copy.
