Sean Owen commented on SPARK-7009:
----------------------------------
I think this could be called "let's require Java 7 soon". In the short term,
building with Java 6 is still fine. To the extent it's not, I think we just
need to drop Java 6 support rather than reconstruct its behavior on Java 7.
> Build assembly JAR via ant to avoid zip64 problems

> Key: SPARK-7009
> URL: https://issues.apache.org/jira/browse/SPARK-7009
> Project: Spark
> Issue Type: Improvement
> Components: Build
> Affects Versions: 1.3.0
> Environment: Java 7+
> Reporter: Steve Loughran
> Original Estimate: 2h
> Remaining Estimate: 2h
>
> SPARK-1911 shows the problem that JDK7+ is using zip64 to build large JARs; a
> format incompatible with Java and pyspark.
> Provided the total number of .class files+resources is <64K, ant can be used
> to make the final JAR instead, perhaps by unzipping the maven-generated JAR
> then rezipping it with zip64=never, before publishing the artifact via maven.
