在运行hadoop后也有回复
[root@hadoop01 hadoop-2.2.0]# hadoop
Usage: hadoop [--config confdir] COMMAND
where COMMAND is one of:
fs run a generic filesystem user client

checknative [-a|-h] check native hadoop and compression libraries availability
distcp <srcurl> <desturl> copy file or directories recursively

Most commands print help when invoked w/o parameters.
