how to disable org.apache.hadoop.mapred.UserLogCleaner

Hi Hadoop user,

I am running hadoop 1.2.1. After completion of job, I am unable to view
userlogs. I can see the following log message in tasktracker log:

2016-02-06 15:19:45,720 INFO org.apache.hadoop.mapred.UserLogCleaner:
Adding job_201601071411_0003 for user-log deletion with
retainTimeStamp:1454838584995
2016-02-06 15:19:45,720 INFO org.apache.hadoop.mapred.UserLogCleaner:
Adding job_201602061240_0002 for user-log deletion with
retainTimeStamp:1454838584995


Is there any way to disable this log deletion?

Also I can see another error in the task tracker

2016-02-06 15:19:46,026 INFO org.apache.hadoop.mapred.TaskTracker: Failed
to get system directory...

Are these two related?

Thanks
Ravikant
