Hudson commented on MAPREDUCE-3834:
-----------------------------------

Integrated in Hadoop-Common-trunk-Commit #1689 (See [https://builds.apache.org/job/Hadoop-Common-trunk-Commit/1689/])
    MAPREDUCE-3834. Changed MR AM to not add the same rack entry multiple times into the container
request table when multiple hosts for a split happen to be on the same rack. Contributed by
Siddarth Seth.
