Hudson commented on MAPREDUCE-1383:
-----------------------------------
Integrated in Hadoop-Mapreduce-trunk #221 (See
[http://hudson.zones.apache.org/hudson/job/Hadoop-Mapreduce-trunk/221/])
. Automates fetching of delegation tokens in File*Formats Distributed Cache
and Distcp. Also, provides a config mapreduce.job.hdfs-servers that the jobs
can populate with a comma separated list of namenodes. The job client
automatically fetches delegation tokens from those namenodes. Contributed by
Boris Shkolnik.
