Subject Re: What exactly are the output_dir/part-00000 semantics (of a streaming job) ?
Date Thu, 12 May 2011 16:49:23 GMT
The creation of files part-nnnnn is atomic. When you run a MR job, these
files are created in directory <output_dir>/_temporary and moved to
<output_dir> after the files is closed for writing. This move is atomic
hence as long as you don't try to read these files from temporary directory
(which I see you are not) you will be fine.
