Subject [jira] [Commented] (BEAM-1789) window can't not use in spark cluster module
Date Thu, 20 Apr 2017 03:32:04 GMT

    [ https://issues.apache.org/jira/browse/BEAM-1789?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15976003#comment-15976003
] 

tianyou commented on BEAM-1789:
-------------------------------

I change _Window.Bound<KV<String,String>> fixWindow = Window.<KV<String,String>>
into(FixedWindows.of(size));_ to _Window.<KV<String,String>>into(FixedWindows.of(size)).triggering(AfterWatermark.pastEndOfWindow().withLateFirings(AfterProcessingTime.pastFirstElementInPane().plusDelayOf(Duration.standardHours(1)))).withAllowedLateness(Duration.standardDays(1)).discardingFiredPanes()_
,But I have the same conclusion

> When I user submit application to spark cluster.In spark UI,I can see log of  totalPc
PCollection  of. after one miniter but I can.t see log of itPc PCollection.
> I use local mode spark,It work well.
> Please help me to resovle this proplems.Thanks!
