Description

build with scala-2.12 with following steps
1. change the pom.xml with scala-2.12

 ./dev/change-scala-version.sh 2.12

2.build with -Pscala-2.12

./dev/make-distribution.sh   --tgz -Pscala-2.12 -Phadoop-2.7  -Pyarn -Pparquet-provided -Dhadoop.version=2.7.3

get the error

/common/unsafe/src/main/java/org/apache/spark/unsafe/Platform.java:172: error: cannot find       symbol
    Cleaner cleaner = Cleaner.create(buffer, () -> freeMemory(memory));

This is because sun.misc.Cleaner has been moved to new location in JDK9. HADOOP-12760 will be the long term fix
