Description
There exists two FakeSchedulerBackend.
$ git grep "class FakeSchedulerBackend" core/src/test/scala/org/apache/spark/HeartbeatReceiverSuite.scala:private class FakeSchedulerBackend( core/src/test/scala/org/apache/spark/scheduler/TaskSchedulerImplSuite.scala:class FakeSchedulerBackend extends SchedulerBackend {
Although `TaskSetManagerSuite` is inside `org.apache.spark.scheduler` package, `import org.apache.spark._` makes Scala 2.13 confused and causes 4 UT failures.
$ build/mvn test -pl core --am -Pscala-2.13 -Dtest=none -DwildcardSuites=org.apache.spark.scheduler.TaskSetManagerSuite ... Tests: succeeded 48, failed 4, canceled 0, ignored 0, pending 0 *** 4 TESTS FAILED ***
This issue aims to fix that by hiding that.
import org.apache.spark.{FakeSchedulerBackend => _, _}
