Arun Mahadevan commented on STORM-2489:
---------------------------------------
[~wangkui], when you get some time can you pull the updated changes and test
again ? The earlier approach might have issues if the clock continuously drifts
and lead to lost and overlapping tuples. I made some changes to address it.

> Key: STORM-2489
> URL: https://issues.apache.org/jira/browse/STORM-2489
> Project: Apache Storm
> Issue Type: Bug
> Components: storm-core
> Affects Versions: 1.0.2
> Environment: windows 10, eclipse, jdk1.7
> Reporter: wangkui
> Assignee: Arun Mahadevan
> Attachments: TumblingWindowIssue.java
>
> Time Spent: 1h 20m
> Remaining Estimate: 0h
>
> The attachment is my test script, one of my test results is:
> ```
> expired=1...55
> get=56...4024
> new=56...4024
> Recived=3969,RecivedTotal=3969
> expired=56...4020
> get=4021...8191
> new=4025...8191
> Recived=4171,RecivedTotal=8140
> SendTotal=12175
> expired=4021...8188
> get=8189...12175
> new=8192...12175
> Recived=3987,RecivedTotal=12127
> ```
> This test result shows that some tuples appear in the expired list directly,
> we lost these data if we just use get() to get tuples, this is the first bug.
> The second: the tuples of get() has overlap, the getNew() seems alright.
> The problem not happen definitely, may need to try several times.
> Actually, I'm newbie about storm, so I'm not sure this is a bug indeed, or, I
> use it in wrong way?
