>
> Currently any user with EXECUTE permission can run getfacl on a file or directory. This Jira adds a check for READ access of user on the inode path. 
> {code:java}
> [root@host ~]$ hdfs dfs -copyFromLocal /etc/a.txt /tmp
> [root@host ~]$ hdfs dfs -setfacl -m user:abc:--- /tmp/a.txt
> {code}
> Since user abc does not have read permission on the file 'cat' command throws Permission Denied error but getfacl executes normally.
> {code:java}
> [abc@host ~]$ hdfs dfs -cat /tmp/a.txt
> cat: Permission denied: user=abc, access=READ, inode="/tmp/a.txt":abc:hdfs:-rw-r--r-- 
> [abc@host ~]$ hdfs dfs -getfacl /tmp/a.txt 
> # file: /tmp/a.txt 
> # owner:root 
> # group: hdfs 
> user::rw- 
> user:abc:--- 
> group::r-- 
> mask::r-- 
> other::r--
> {code}
