      Description

      If I pass an invalid symlink as -Dmapred.cache.files=/user/knoguchi/onerecord.txt#abc/abc

      Task only reports a WARN and goes on.

       
      2010-09-16 21:38:49,782 INFO org.apache.hadoop.mapred.TaskRunner: Creating symlink: /0/tmp/mapred-local/taskTracker/knoguchi/distcache/-5031501808205559510_-128488332_1354038698/abc-nn1.def.com/user/knoguchi/onerecord.txt <- /0/tmp/mapred-local/taskTracker/knoguchi/jobcache/job_201008310107_15105/attempt_201008310107_15105_m_000000_0/work/./abc/abc
      2010-09-16 21:38:49,789 WARN org.apache.hadoop.mapred.TaskRunner: Failed to create symlink: /0/tmp/mapred-local/taskTracker/knoguchi/distcache/-5031501808205559510_-128488332_1354038698/abc-nn1.def.com/user/knoguchi/onerecord.txt <- /0/tmp/mapred-local/taskTracker/knoguchi/jobcache/job_201008310107_15105/attempt_201008310107_15105_m_000000_0/work/./abc/abc
      

      I believe we should fail the task at this point.
