---------------------------------------
Summary: Warnings about "MaxPermSize" parameter when building with
Maven and Java 8
Key: SPARK-17421
URL: https://issues.apache.org/jira/browse/SPARK-17421
Project: Spark
Issue Type: Bug
Components: Build
Reporter: Frederick Reiss
Priority: Minor
When building Spark with {{build/mvn}} or {{dev/run-tests}}, a Java warning
appears repeatedly on STDERR:
{{OpenJDK 64-Bit Server VM warning: ignoring option MaxPermSize=512M; support
was removed in 8.0}}
This warning is due to {{build/mvn}} adding the {{-XX:MaxPermSize=512M}} option
to {{MAVEN_OPTS}}. When compiling with Java 7, this parameter is essential.
With Java 8, the parameter leads to the warning above.
Because {{build/mvn}} adds {{MaxPermSize}} to {{MAVEN_OPTS}}, even if that
environment variable doesn't contain the option, setting {{MAVEN_OPTS}} to a
string that does not contain {{MaxPermSize}} has no effect.
