> After running a job that died after only writing a little bit of logs, the tasklog servlet shows an empty log.  In the log directory, however, there are non-empty stderr and stdout logs:
> $ ls -la
> total 92
> drwxrwsr-x  2 mapreduce mapreduce  4096 Mar 19 16:24 .
> drwxrwsr-x 95 mapreduce mapreduce 69632 Mar 19 16:24 ..
> -rw-r--r--  1 mapreduce mapreduce    78 Mar 19 16:24 log.index
> -rw-rw-r--  1 mapreduce mapreduce   350 Mar 19 16:24 stderr
> -rw-rw-r--  1 mapreduce mapreduce  4413 Mar 19 16:24 stdout
> $ cat log.index 
> LOG_DIR:attempt_200902160142_0040_m_000000_3
