I installed hadoop using cloudera manager parcels. I always have this
If I disabled yarn log aggregation, I got this error message when I click a
link of maptask or reducetask in jobhistory:
Aggregation is not enabled. Try the nodemanager at XXXX:8041
And if I enabled log aggregation, the log folder on
hdfs:/tmp/logs/bwang/logs/application_XXX was owned by my account like this.
drwxrwx--- - bwang supergroup 0 2013-10-24 16:25
When I clicked a link of finished maptask/reducetask, I couldn't get the
logs, and In jobhistory log under /var/log/hadoop-mapreduce, there was an
exception like this:
2013-10-24 16:26:57,468 ERROR org.apache.hadoop.yarn.webapp.View: Error
getting logs for job_1382656840471_0002
org.apache.hadoop.security.AccessControlException: Permission denied:
If manually change the permission, the log can be returned.
What's wrong with my installation?
