> Add the statistics of pending checkpoints as a gauge metric. When the
> checkpoint appears not to be completed, this metric would help to get the
> state of a pending checkpoint , e.g which task did not complete the
> checkpoint.
> The statistic will be as the follows：
> checkpointID,
> Number Of Acknowledged Tasks,
> Number Of Not yet Acknowledged Tasks,
> The detail of not yet acknowledged JobVertexID, taskID
