Dongjoon Hyun updated SPARK-21578:
----------------------------------
Description:
Due to SI-8479, [SPARK-1093|https://issues.apache.org/jira/browse/SPARK-21578]
introduced redundant [SparkContext
constructors|https://github.com/apache/spark/blob/master/core/src/main/scala/org/apache/spark/SparkContext.scala#L148-L181].
However, [SI-8479|https://issues.scala-lang.org/browse/SI-8479] is already
fixed in Scala 2.10.5 and Scala 2.11.1.
The real reason to provide this constructor is that Java code can access
`SparkContext` directly. It's Scala behavior, SI-4278. So, this PR adds an
explicit testsuite, `JavaSparkContextSuite` to prevent future regression, and
fixes the outdate comment, too.

Due to SI-8479,
[SPARK-1093|https://github.com/apache/spark/blob/master/core/src/main/scala/org/apache/spark/SparkContext.scala#L148-L181]
introduced redundant constructors.
Since [SI-8479|https://issues.scala-lang.org/browse/SI-8479] is fixed in Scala
2.10.5 and Scala 2.11.1. We can remove them safely.
