The cleaner should remain up while the sparkcontext is still active (not
stopped). However, here it seems you are stopping the sparkContext
("ssc.stop(true)"), the cleaner should be stopped. However, there was a bug
earlier where some of the cleaners may not have been stopped when the
context is stopped. What version are you using. If it is 0.9.1, I can see
that the cleaner in
ShuffleBlockManager<https://github.com/apache/spark/blob/v0.9.1/core/src/main/scala/org/apache/spark/storage/ShuffleBlockManager.scala>is
not stopped, so it is a bug.
