Hi All,
I have written a set of codes that are supposed to do map reduce Job. But when i run them i get some errors which am not able to resolve please do help me to run this program successfully.
Errors :
1. Exception in
thread "main" org.apache.hadoop.mapred.FileAlreadyExistsException
2. The mapping part is running 100% but the reducer is not running.
Thanks in advance,
JasonJ.
