Owen O'Malley updated MAPREDUCE-2804:
-------------------------------------
Attachment: mr-2804.patch
Fundamentally, there were two problems:
1. The logging message was less than useful.
2. There is a race condition when java's primitives are used to change
permissions on a file.
This patch fixes the log messages to be much clearer about what is going wrong
and removes the extra chmod of the job directory. It was that chmod that was
causing the creation of the symlinks of a different task to fail when they were
launching at the same time.
> "Creation of symlink to attempt log dir failed." message is not useful

> In attempting to qualify the 204 RC2 release, my tasktracker logs are filled
> with the above message. I'd love to do something about it, but since it
> doesn't tell me what exactly it is trying to symlink I cannot unless I dig
> into the source code.
