Sean Owen created SPARK-27536: --------------------------------- Summary: Code improvements for 3.0: existentials edition Key: SPARK-27536 URL: https://issues.apache.org/jira/browse/SPARK-27536 Project: Spark Issue Type: Improvement Components: ML, Spark Core, SQL, Structured Streaming Affects Versions: 3.0.0 Reporter: Sean Owen Assignee: Sean Owen
The Spark code base makes use of 'existential types' in Scala, a language feature which is quasi-deprecated -- it generates a warning unless scala.language.existentials is imported, and there is talk of removing it from future Scala versions: https://contributors.scala-lang.org/t/proposal-to-remove-existential-types-from-the-language/2785 We can get rid of most usages of this feature with lots of minor changes to the code. A PR is coming to demonstrate what's involved. -- 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
