Subject Re: How to get the intermediate mapper output file name
Date Mon, 03 Jun 2013 09:42:00 GMT
Hi Samir,

File naming is defined in FileOutputFormat class and there is property
mapreduce.output.basename
which you can use to tweak things with file naming.

Please check this code
http://grepcode.com/file/repository.cloudera.com/content/repositories/releases/com.cloudera.hadoop/hadoop-core/0.20.2-737/org/apache/hadoop/mapreduce/lib/output/FileOutputFormat.java#FileOutputFormat
for
more details (line 272).

HTH
