Summary: Eliminate warnings from deprecated constructors of
java.lang.Integer and java.lang.Double
Key: SPARK-30676
URL: https://issues.apache.org/jira/browse/SPARK-30676
Project: Spark
Issue Type: Sub-task
Components: Spark Core
Affects Versions: 3.0.0
Reporter: Maxim Gekk
The constructors of java.lang.Integer and java.lang.Double has been deprecated
already, see
[https://docs.oracle.com/javase/9/docs/api/java/lang/Integer.html]. The
following warnings are printed while compiling Spark:
{code}
1. RDD.scala:240: constructor Integer in class Integer is deprecated: see
corresponding Javadoc for more information.
2. MutableProjectionSuite.scala:63: constructor Integer in class Integer is
deprecated: see corresponding Javadoc for more information.
3. UDFSuite.scala:446: constructor Integer in class Integer is deprecated: see
corresponding Javadoc for more information.
4. UDFSuite.scala:451: constructor Double in class Double is deprecated: see
corresponding Javadoc for more information.
5. HiveUserDefinedTypeSuite.scala:71: constructor Double in class Double is
deprecated: see corresponding Javadoc for more information.
{code}
The ticket aims to replace the constructors by the valueOf methods, or maybe
by other ways.
