> This is caused due to:
> 1. SingleCheckpointBarrierHandler first receive a BarrierAnnouncement, which
> would call checkNewCheckpoint to reset the currentCheckpointId and the
> alignedChannels.
> 2. SingleCheckpointBarrierHandler then received an EndOfPartition, which
> would add the channel to the alignedChannels.
> 3. SingleCheckpointBarrierHandler then received a barrier, which would found
> that the alignedChannels is already not empty, then it would skip the
> markAlignmentStart.
> We might change 3 to judge if this is the first barrier to receive.
