> If users don't specify the perm of an acl when using the FsShell's setfacl command, a
fatal internal error ArrayIndexOutOfBoundsException will be thrown.
> {code}
> [root@hdfs-nfs ~]# hdfs dfs -setfacl -m user:bob: /user/hdfs/td1
> -setfacl: Fatal internal error
> java.lang.ArrayIndexOutOfBoundsException: 2

<acl_spec> <path>]
> [root@hdfs-nfs ~]#
