Hi,
I need a help very bad. I got an HDFS permission error by starting to run hadoop job org.apache.hadoop.security.AccessControlException: Permission denied: user=wp, access=WRITE, inode="":hadoop:supergroup:rwxr-xr-x I have the right permission to read and write files to my own hadoop user directory. It works fine when I use hadoop fs -put. The job input and output are all from my own hadoop user directory. It seems that when a job starts running, some data need to be written into some directory, and I don't have the permission to that directory. It is strange that the inode does not show which directory it is. Why does hadoop write something to a directory with my name secretly? Do I need to be set a particular user group? Many Thanks.. Vivian
