Frederick Reiss created SPARK-17421: ---------------------------------------
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. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
