Hudson commented on MAPREDUCE-3810:
-----------------------------------

Integrated in Hadoop-Hdfs-0.23-Commit #488 (See [https://builds.apache.org/job/Hadoop-Hdfs-0.23-Commit/488/])
    Merge -c 1241205 from trunk to branch-0.23 to fix MAPREDUCE-3810. Performance tweaks -
reduced logging in AM and defined hascode/equals for ResourceRequest & Priority.
