Hello,
I am trying to build Spark from source using the following:
export MAVEN_OPTS=-Xmx2g -XX:MaxPermSize=512M
-XX:ReservedCodeCacheSize=512m
mvn -Pyarn -Phadoop-2.3 -Dhadoop.version=2.3.0 -Phive -DskipTests clean
package
this works OK with branch-1.1, when I switch to branch-1.2, I get the
following error while building spark-core:

inferred existential type (org.apache.spark.scheduler.DirectTaskResult[_$1],
Int) forSome { type _$1 }, which cannot be expressed by wildcards, should
be enabled
by making the implicit value scala.language.existentials visible.
This can be achieved by adding the import clause 'import
scala.language.existentials'
or by setting the compiler option -language:existentials.
See the Scala docs for value scala.language.existentials for a discussion
why the feature should be explicitly enabled.
