Shixiong Zhu commented on SPARK-12206:
--------------------------------------
Because only batches that are multiple times of slide duration will run,
"StreamingJobProgressListener" cannot get info of other batches.
/cc [~tdas] what do you think about this one?
> Streaming WebUI shows incorrect batch statistics when using Window operations
> -----------------------------------------------------------------------------
>
> Key: SPARK-12206
> URL: https://issues.apache.org/jira/browse/SPARK-12206
> Project: Spark
> Issue Type: Bug
> Components: Streaming
> Affects Versions: 1.5.1
> Reporter: Anand Iyer
> Priority: Minor
> Attachments: streaming-webui.png
>
>
> I have a streaming app that uses the Window(...) function to create a sliding
> window, and perform transformations on the window'd DStream.
> The Batch statistics section of the Streaming UI starts displaying stats for
> each Window, instead of each micro-batch. Is that expected behavior?
> The "Input Size" column shows incorrect values. The streaming application is
> receiving about 1K events/sec. However, the "Input Size" column shows values
> in the single digits or low double digits.
