Thanks Nitin. I believe the config key you mentioned controls the task attempts logs that go under - ${hadoop.log.dir}/userlogs.
The ones that I mentioned are the job history logs that go under - ${hadoop.log.dir}/history and are specified by the key "hadoop.job.history.location". Are these cleaned up based on "mapred.userlog.retain.hours" too? Also, this is what I am seeing in history dir Available Conf files - Mar 3rd - April 5th Available Job files - Mar 3rd - April 3rd There is no job file present after the 3rd of April, but conf files continue to be written.
