Subject [jira] [Created] (SPARK-31004) Show message for empty Streaming Queries instead of empty timelines and histograms.
Date Mon, 02 Mar 2020 02:55:00 GMT
Kousuke Saruta created SPARK-31004:
--------------------------------------

             Summary: Show message for empty Streaming Queries instead of empty timelines
and histograms.
                 Key: SPARK-31004
                 URL: https://issues.apache.org/jira/browse/SPARK-31004
             Project: Spark
          Issue Type: Improvement
          Components: Structured Streaming, Web UI
    Affects Versions: 3.0.0
            Reporter: Kousuke Saruta
            Assignee: Kousuke Saruta


If a Streaming Query has no batches, StreamingQueryStatisticsPage shows empty timelines and
histograms. 
It's ugly and better to show a message that clearly says "No visualization information available".
