@dahaian I think this is the issue of Eclipse, you can open 
'JavaConsumerStrategySuite.java' file, remove the '.mapValues'  and then retype 
'.mapValues' again, save file to recompile, it will resolve this issue. I 
resolved it by this way.

@srowen I want to know which IDE do you use? Eclipse or IDEA?

This isn't the right place to ask, and `master` builds fine, so you should 
probably use that.

That code didn't change in the update for Java 8, and the error itself 
doesn't sound directly like a Java language level issue. (Although you see an 
anonymous function here, actually, this is an instance that could not change.) 
I don't see a compile error locally or on any Jenkins build either. Check your 
local env? clean build?

https://github.com/apache/spark/pull/16964
  
@srowen after update to master, in Eclipse IDE, there is an error in 
JavaConsumerStrategySuite.java line 52:

`final Map offsets = new HashMap<>();
offsets.put(tp1, 23L);
final scala.collection.Map sOffsets =
  JavaConverters.mapAsScalaMapConverter(offsets).asScala().mapValues(
new scala.runtime.AbstractFunction1() {
  @Override
  public Object apply(Long x) {
return (Object) x;
  }
}
  );`

Error is as follows:
**The method mapValues(Function1) is ambiguous for the type 
Map**

Is it related to updating Java 7 to 8?
