------------------------------
Summary: TumblingProcessingTimeWindows can't set offset
parameter to a negative value
Key: FLINK-6906
URL: https://issues.apache.org/jira/browse/FLINK-6906
Project: Flink
Issue Type: Bug
Components: DataStream API
Affects Versions: 1.2.1, 1.3.0, 1.2.0, 1.2.2
Reporter: bmnouwq
Excuse my English.
In the DataStream API,I specify
{code:java}
org.apache.flink.streaming.api.windowing.assigners.TumblingProcessingTimeWindows
{code}
an offset of a negative value such as Time.hours(-8),When trying to submit
the Job will throw IllegalArgumentException "TumblingProcessingTimeWindows
parameters must satisfy 0 <= offset < size" .
This is problematic for living in somewhere which is not using UTC-00:00 time.
{code:java}
org.apache.flink.streaming.api.windowing.assigners.SlidingEventTimeWindows
{code},
{code:java}
org.apache.flink.streaming.api.windowing.assigners.SlidingProcessingTimeWindows
{code},
{code:java}
org.apache.flink.streaming.api.windowing.assigners.TumblingEventTimeWindows
{code} has the same problem.
We should use the offset absolute value to compare with the size in the
construct method.
