Hi

I have a query regarding MapReduce Job Output
Let say i have multiple reducers (24) for my job. While after completion of 15 reducers my job get failed and the rest 9 reducers wont able to write data in hdfs.
So the output created by the rest 15 reducers would remain in my output directory path of hdfs or they get also removed as my all reducers not able to process and job get failed in between.


Thanks

Ideally output of 15 reducers should be availalable in HDFS.
 
It is sorta covered in the JavaRanch Style Guide.
