Subject [GitHub] spark pull request: [SPARK-7826][CORE] Suppress extra calling getC...

Github user ueshin commented on the pull request:
    @srowen, Thank you for your checking.
    1. To check the parent stages are missing or not, we only have to check the location of
RDD that has `ShuffleDependency` because narrow-depending RDDs would be the same location,
so I moved the calling `getCacheLocs` into the `case shufDep`.
    2. I was afraid that the dependency graph would become bigger (if there are a lot of `union`
or `zipPartitions`, etc.) so I added checking the location at the point the RDD has more than
1 dependencies.
      * we might not need [line 389](
if we don't have to consider the case.
