> [error] /home/jenkins/workspace/Spark-Master-Scala211-Compile/sql/catalyst/src/main/java/org/apache/spark/sql/execution/UnsafeExternalRowSorter.java:135: error: <anonymous org.apache.spark.sql.execution.UnsafeExternalRowSorter$1> is not abstract and does not override abstract method <B>minBy(Function1<InternalRow,B>,Ordering<B>) in TraversableOnce
> [error]       return new AbstractScalaRowIterator() {
> [error]                                             ^
> [error]   where B,A are type-variables:
> [error]     B extends Object declared in method <B>minBy(Function1<A,B>,Ordering<B>)
> [error]     A extends Object declared in interface TraversableOnce
> [error] 1 error
> [error] Compile failed at Jul 14, 2015 2:26:25 PM [26.443s]
> {code}
> It turns out that this can be fixed by making AbstractScalaRowIterator into a concrete class instead of an abstract class.
