我想我已经正确安装了hadoop。如果我执行jps，我可以看到namenode和datanode，没有问题。
当我输入hadoop fs -ls .时，我得到错误:
Java HotSpot(TM) 64-Bit Server VM warning: You have loaded library /opt/db/hadoop-2.4.1/lib/native/libhadoop.so.1.0.0 which might have disabled stack guard. The VM will try to fix the stack guard now.
It's highly recommended that you fix the library with 'execstack -c <libfile>', or link it with '-z noexecstack'.

当我输入hadoop dfs -ls .时，我得到错误:
DEPRECATED: Use of this script to execute hdfs command is deprecated.
Instead use the hdfs command for it.

当我输入hadoop hdfs -ls .时，我得到错误:
Error: Could not find or load main class hdfs
不管我是否放了'。'或'/'或我所在的任何目录
这是什么意思?我怎样才能得到正常的、预期的输出?我错过了什么?
使用
hdfs dfs -ls ...
我不认为有hadoop hdfs这种东西
按如下方式使用命令
bin/hadoop fs -ls /
