Description

In MR1, org.apache.hadoop.mapreduce.lib.output.FileOutputFormat.checkOutputSpecs throws org.apache.hadoop.mapred.FileAlreadyExistsException but now it throws org.apache.hadoop.fs.FileAlreadyExistsException instead, making them incompatible.

In MR1, org.apache.hadoop.mapreduce.lib.output.FileOutputFormat.setOutputPath doesn't throw any exceptions but now it throws an IOException, making them incompatible.
