Michael Armbrust created SPARK-27911: ----------------------------------------
Summary: PySpark Packages should automatically choose correct scala version Key: SPARK-27911 URL: https://issues.apache.org/jira/browse/SPARK-27911 Project: Spark Issue Type: New Feature Components: PySpark Affects Versions: 2.4.3 Reporter: Michael Armbrust Today, users of pyspark (and Scala) need to manually specify the version of Scala that their Spark installation is using when adding a Spark package to their application. This extra configuration confusing to users who may not even know which version of Scala they are using (for example, if they installed Spark using {{pip}}). The confusion here is exacerbated by releases in Spark that have changed the default from {{2.11}} -> {{2.12}} -> {{2.11}}. https://spark.apache.org/releases/spark-release-2-4-2.html https://spark.apache.org/releases/spark-release-2-4-3.html Since Spark can know which version of Scala it was compiled for, we should give users the option to automatically choose the correct version. This could be as simple as a substitution for {{$scalaVersion}} or something when resolving a package (similar to SBTs support for automatically handling scala dependencies). Here are some concrete examples of users getting it wrong and getting confused: https://github.com/delta-io/delta/issues/6 https://github.com/delta-io/delta/issues/63 -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
