How can you create a file inside a hadoop map-reduce job?

Question

I searched the web, but all I found was a site that claimed that it could be done. It didn't say how.

Answer 1

FileSystem fs = FileSystem.get(conf);
Path path = new Path("/my/path/file")
OutputStream os = fs.create(path)
// write to os
os.close()

Answer 2
