Prashant Sharma commented on SPARK-3359:
----------------------------------------

I guess this will happen along with scala 2.11 upgrade. Since the old version does not work with scala 2.11.

> It seems that Java 8 is stricter on JavaDoc. I got many error messages like
> {code}
> [error] /Users/meng/src/spark-mengxr/core/target/java/org/apache/hadoop/mapred/SparkHadoopMapRedUtil.java:2: error: modifier private not allowed here
> [error] private abstract interface SparkHadoopMapRedUtil {
> [error]                  ^
> {code}
> This is minor because we can always use Java 6/7 to generate the doc.
