Hi, I have a job that uses processing time session window with inactivity gap of 60ms where I intermittently run into the following exception. I'm trying to figure out what happened here. Haven't been able to reproduce this scenario. Any thoughts?
java.lang.UnsupportedOperationException: *The end timestamp of a processing-time window cannot become earlier than the current processing time by merging. Current processing time: 1560493731808 window: TimeWindow{start=1560493731654, end=1560493731778}* at org.apache.flink.streaming.runtime.operators.windowing.WindowOperator$2.merge(WindowOperator.java:325) at org.apache.flink.streaming.runtime.operators.windowing.WindowOperator$2.merge(WindowOperator.java:311) at org.apache.flink.streaming.runtime.operators.windowing.MergingWindowSet.addWindow(MergingWindowSet.java:212) at org.apache.flink.streaming.runtime.operators.windowing.WindowOperator.processElement(WindowOperator.java:311) at org.apache.flink.streaming.runtime.io.StreamInputProcessor.processInput(StreamInputProcessor.java:202) at org.apache.flink.streaming.runtime.tasks.OneInputStreamTask.run(OneInputStreamTask.java:105) at org.apache.flink.streaming.runtime.tasks.StreamTask.invoke(StreamTask.java:300) at org.apache.flink.runtime.taskmanager.Task.run(Task.java:711) at java.lang.Thread.run(Thread.java:745) -- Warm Regards, Abhishek Jain
