Description

This happens with the first task of a job being localized on this TT. TT doesn't check if the file on DFS is fresh according to the timestamps set in job-conf during submission. After the first task incorrectly gets localized, all further tasks fail on this TT as expected.

Found this issue while trying to improve test-case for MAPREUCE-913.
