Todd Lipcon commented on MAPREDUCE-2238:
----------------------------------------

Another clue on this one:

root@ubuntu64-build01:/home/hudson/production/workspace/CDH3-todd-security/build/test# stat logs/userlogs/job_20110116195813351_0001/attempt_20110116195813351_0001_m_000001_0/
  File: `logs/userlogs/job_20110116195813351_0001/attempt_20110116195813351_0001_m_000001_0/'

Change: 2011-01-16 19:58:49.000000000 -0800

Note the change time. Now looking at what tests ran during that change time:

root@ubuntu64-build01:/home/hudson/production/workspace/CDH3-todd-security/build/test# grep -l '2011-01-16 20:58:4' *
TEST-org.apache.hadoop.mapred.TestTaskLogsTruncater.xml

Seems like TestTaskLogsTruncater is probably the culprit. Also suspicious is that that same test failed a test run a few builds prior to this.

> The MR hudson job is failing, looks like it's due to a test chmod'ing a build directory so the checkout can't clean the build dir.
