Hudson commented on MAPREDUCE-3815:
-----------------------------------
Integrated in Hadoop-Mapreduce-0.23-Build #185 (See [https://builds.apache.org/job/Hadoop-Mapreduce-0.23-Build/185/])
MAPREDUCE-3815. Fixed MR AM to always use hostnames and never IPs when requesting containers
so that scheduler can give off data local containers correctly. Contributed by Siddarth Seth.
