Apache Spark reassigned SPARK-24807:
------------------------------------
Assignee: (was: Apache Spark)
> Adding files/jars twice: output a warning and add a note
> --------------------------------------------------------
>
> Key: SPARK-24807
> URL: https://issues.apache.org/jira/browse/SPARK-24807
> Project: Spark
> Issue Type: Improvement
> Components: Spark Core
> Affects Versions: 2.3.1
> Reporter: Maxim Gekk
> Priority: Trivial
>
> In current version of Spark (2.3.x), one file/jar can be added only once.
> Next additions of the same path are silently ignored. This behavoir is not
> properly documented:
> https://spark.apache.org/docs/2.3.1/api/scala/index.html#org.apache.spark.SparkContext
> This confuses our users and support teams in our company. The ticket aims to
> output a warning which should clearly state that second addition of the same
> path is not supported now.
