-------------------------------------
Attachment: HADOOP-12026.001.patch

> Issue Type: Improvement

> This patch has the changes to Common needed for MAPREDUCE-347, which prints a
> message rather than the whole stack trace when the output directory already
> exists. The attached patch adds the OutputDirectoryAlreadyExistsException,
> and the handling of this exception in RunJar.java. Modified tests are
> included in the Mapreduce part of this patch, which depends on the changes to
> Common. If you would like me to upload the entire patch with the Mapreduce
> changes here, please let me know. (Otherwise I'll add the Mapreduce changes
> to the MAPREDUCE-347 issue after this patch is accepted.)
> The Mapreduce changes are necessary for the patch to really work. They throw
> the exception when the output directory is found to exist in
> FileOutputFormat.java. They also will modify a test and ExampleDriver.java.
