Hudson commented on MAPREDUCE-3931:
-----------------------------------
Integrated in Hadoop-Mapreduce-0.23-Commit #613 (See
[https://builds.apache.org/job/Hadoop-Mapreduce-0.23-Commit/613/])
MAPREDUCE-3931. Changed PB implementation of LocalResource to take locks so
that race conditions don't fail tasks by inadvertantly changing the timestamps.
