Tasklog servlet doesn't display any logs when logs are short
------------------------------------------------------------
Key: HADOOP-5537
URL: https://issues.apache.org/jira/browse/HADOOP-5537
Project: Hadoop Core
Issue Type: Bug
Components: mapred
Affects Versions: 0.19.0
Reporter: Michael Bieniosek
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
