Hudson commented on MAPREDUCE-3714:
-----------------------------------

Integrated in Hadoop-Hdfs-trunk #936 (See [https://builds.apache.org/job/Hadoop-Hdfs-trunk/936/])
    MAPREDUCE-3714. Fixed EventFetcher and Fetcher threads to shut-down properly so that reducers don't hang in corner cases. (vinodkv)
