[jira] Issue Comment Edited: (HADOOP-1320) Rewrite 'random-writer' to use '-reducer NONE'

I realise, rather belatedly, that changing the filename of the output of {{MapTask.DirectMapOutputCollector}} to make it compatible with that of {{ReduceTask}} results in changes to output of streaming's *-reducer NONE* too (e.g. I had to fix {{org.apache.hadoop.streaming.TestStreamReduceNone}}) - is this a big concern for streaming users? Runping/Arkady?

Re: [jira] Issue Comment Edited: (HADOOP-1320) Rewrite 'random-writer' to use '-reducer NONE'

Posted by Arkady Borkovsky <ar...@yahoo-inc.com>.
I do not think that anyone relies on part names produced by reducer - 
NONE.
