hi,all:
My environment : Centos7.2 hadoop2.7.3 jdk1.8 kerberos 1.13.2-12.el7_2
my hadoop user is hadoop,now I can startup hdfs with sbin/start-dfs.sh and I 
can see data node from the web.
but when I try to hdfs dfs -ls / ,I got error:

[hadoop@dmp1 ~]$ hdfs dfs -ls /

It's because of my jdk is 1.8 ?
