Sean Owen resolved SPARK-17421. ------------------------------- Resolution: Fixed Fix Version/s: 2.1.0 2.0.1 Issue resolved by pull request 15005 [https://github.com/apache/spark/pull/15005] > Document 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: Improvement > Components: Build > Reporter: Frederick Reiss > Priority: Trivial > Fix For: 2.0.1, 2.1.0 > > > 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
