-----------------------------------

Integrated in Hadoop-Mapreduce-trunk-Commit #1487 (See [https://builds.apache.org/job/Hadoop-Mapreduce-trunk-Commit/1487/])
    MAPREDUCE-3586. Modified CompositeService to avoid duplicate stop operations thereby solving
race conditions in MR AM shutdown. (vinodkv)
