Hudson commented on MAPREDUCE-3716:
-----------------------------------

Integrated in Hadoop-Mapreduce-trunk-Commit #1636 (See [https://builds.apache.org/job/Hadoop-Mapreduce-trunk-Commit/1636/])
    MAPREDUCE-3716. Fixing YARN+MR to allow MR jobs to be able to use java.io.File.createTempFile to create temporary files as part of their tasks. Contributed by Jonathan Eagles.
