[jira] [Created] (FLINK-20087) CheckpointCoordinator waits until all tasks finish initialization of states to trigger checkpoint

Jiayi Liao created FLINK-20087:
----------------------------------

             Summary: CheckpointCoordinator waits until all tasks finish initialization of states to trigger checkpoint
                 Key: FLINK-20087
                 URL: https://issues.apache.org/jira/browse/FLINK-20087
             Project: Flink
          Issue Type: Improvement
          Components: Runtime / Checkpointing
    Affects Versions: 1.9.0
            Reporter: Jiayi Liao


{{CheckpointCoordinator}} will start triggering checkpoint after all tasks send RUNNING status to JobMaster. However, the {{initializeState}} could be time-expensive(a few minutes), for example the task needs to rescale with multiple old tasks' rocksdb data. During this process, the triggering of checkpoints are meaningless.
