I tried setting "mapreduce.fileoutputcommitter.marksuccessfuljobs=false" in configuration and it worked.
Found information about this in a JIRA ticket as well: https://issues.apache.org/jira/browse/MAPREDUCE-947 Thank you Aniket.

To avoid generation of _log folder, I can set the configuration parameter "hadoop.job.history.user.location" with value as "none". But, I don't know how to avoid the creation of _SUCCESS folder. Can anyone please help. Note: For now, as a work around, I am using FileSystem commands at the end of job to delete the folder manually.
