hi,
I set the mode of a directory on hdfs to 'rwxrwx---' ,however, I was denied to access the directory by dfs shell as a user in the same group . Did I make a mistake?
 
[raw@hadoop-test-3 ~]$ hadoop fs -ls /user/query  
ls: could not get get listing for 'hdfs://192.168.32.23:8020/user/query' : org.apache.hadoop.security.AccessControlException: Permission denied: user=raw, access=READ_EXECUTE, inode="query":query:raw:rwxrwx---
[raw@hadoop-test-3 ~]$ bash -c groups
raw

Try adding user [raw] to the hadoop group. For now, user [raw] belongs to the “others” where there are no read|write|execute permissions are set.
