[jira] [Updated] (SPARK-33285) Too many "Auto-application to `()`
is deprecated." related compilation warnings
[ https://issues.apache.org/jira/browse/SPARK-33285?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Yang Jie updated SPARK-33285:
-----------------------------
Description:
There are too many "Auto-application to `()` is deprecated." related compilation warnings when compile with Scala 2.13 like
{code:java}
[WARNING] [Warn] /spark-src/core/src/test/scala/org/apache/spark/PartitioningSuite.scala:246: Auto-application to `()` is deprecated. Supply the empty argument list `()` explicitly to invoke method stdev,
or remove the empty argument list from its definition (Java-defined methods are exempt).
In Scala 3, an unapplied method like this will be eta-expanded into a function.
[WARNING] [Warn] /spark-src/core/src/test/scala/org/apache/spark/PartitioningSuite.scala:247: Auto-application to `()` is deprecated. Supply the empty argument list `()` explicitly to invoke method variance,
or remove the empty argument list from its definition (Java-defined methods are exempt).
In Scala 3, an unapplied method like this will be eta-expanded into a function.
[WARNING] [Warn] /spark-src/core/src/test/scala/org/apache/spark/PartitioningSuite.scala:247: Auto-application to `()` is deprecated. Supply the empty argument list `()` explicitly to invoke method popVariance,
or remove the empty argument list from its definition (Java-defined methods are exempt).
In Scala 3, an unapplied method like this will be eta-expanded into a function.
[WARNING] [Warn] /spark-src/core/src/test/scala/org/apache/spark/PartitioningSuite.scala:248: Auto-application to `()` is deprecated. Supply the empty argument list `()` explicitly to invoke method stdev,
or remove the empty argument list from its definition (Java-defined methods are exempt).
In Scala 3, an unapplied method like this will be eta-expanded into a function.
[WARNING] [Warn] /spark-src/core/src/test/scala/org/apache/spark/PartitioningSuite.scala:248: Auto-application to `()` is deprecated. Supply the empty argument list `()` explicitly to invoke method popStdev,
or remove the empty argument list from its definition (Java-defined methods are exempt).
In Scala 3, an unapplied method like this will be eta-expanded into a function.
{code}
Maybe these will mask some of the more important compilation warnings
