Apache Spark reassigned SPARK-17437:
------------------------------------
Assignee: (was: Apache Spark)
> uiWebUrl is not accessible to JavaSparkContext or pyspark.SparkContext
> ----------------------------------------------------------------------
>
> Key: SPARK-17437
> URL: https://issues.apache.org/jira/browse/SPARK-17437
> Project: Spark
> Issue Type: Improvement
> Components: Java API, PySpark, Web UI
> Affects Versions: 2.0.0
> Reporter: Adrian Petrescu
>
> The Scala version of {{SparkContext}} has a handy field called {{uiWebUrl}}
> that tells you which URL the SparkUI spawned by that instance lives at. This
> is often very useful because the value for {{spark.ui.port}} in the config is
> only a suggestion; if that port number is taken by another Spark instance on
> the same machine, Spark will just keep incrementing the port until it finds a
> free one. So, on a machine with a lot of running PySpark instances, you often
> have to start trying all of them one-by-one until you find your application
> name.
> Scala users have a way around this with {{uiWebUrl}} but Java and Python
> users do not. This ticket (and the attached PR) fix this in the most
> straightforward way possible, simply propagating this field through the
> {{JavaSparkContext}} and into pyspark through the Java gateway.
> Please let me know if any additional documentation/testing is needed.
