---------------------------------
Hi [~liliwei], very thanks for opening the PR!
There should be once a discussion regarding how to deal with processing time at
the end of stream, might be related to
[https://cwiki.apache.org/confluence/display/FLINK/FLIP-134%3A+Batch+execution+for+the+DataStream+API],
I'll also have a check of the current status.

> This can correctly calculate the following interval result : 0-10s 10-20s
> 20-30s 30-40s 40-50s
> But this lost data which was send in 50-60s.
> Because when the first window ends, the time is 59.9999s, it is not equal to
> window-end-time(60s).So it will not enter the if judgment.
