Allen Wittenauer resolved MAPREDUCE-212.
----------------------------------------
Resolution: Won't Fix
I'm going to close this as won't fix. In some cases, Hadoop has slowly been
moving log files over to avro. In other cases, the logs are 3rd
party/ecosystem controlled and could be in the format for that project.
> want InputFormat for task logs

> URL: https://issues.apache.org/jira/browse/MAPREDUCE-212
> Project: Hadoop Map/Reduce
> Issue Type: New Feature

> We should provide an InputFormat implementation that includes all the task
> logs from a job. Folks should be able to do something like:
> job = new JobConf();
> job.setInputFormatClass(TaskLogInputFormat.class);
> TaskLogInputFormat.setJobId(jobId);
> ...
> Tasks should ideally be localized to the node that each log is on.
> Examining logs should be as lightweight as possible, to facilitate debugging.
> It should not require a copy to HDFS. A faster debug loop is like a faster
> search engine: it makes people more productive. The sooner one can find that,
> e.g., most tasks failed with a NullPointerException on line 723, the better.
