Hi, Our jobtracker disable the history logging function due to an error: 2010-10-13 18:41:34,559 ERROR org.apache.hadoop.mapred.JobHistory: Failed creating job history log file, disabling history org.apache.hadoop.security.AccessControlException: org.apache.hadoop.security.AccessControlException: Permission denied: user=ethyagarajan, access=WRITE, inode="10":middleware:supergroup:rwxr-xr-x
Could anybody tell me why this error occured and how to recover the history logging function without restarting jobtracker? Thanks in advance!
