makefile move command make it do not work - makefile

Question

I write a makefile to run hadoop in Ubuntu. When the inputscommand is follow run:, it works. But if I move it down to the below of hdfs dfs -rm -f -r $(EXAMPLE_DIR), it failed and shows the error message :
make: inputs: Command not found.I am new to Ubuntu so I do not know how to fix the problem after searching the result because this error has too many possible causes. The makefile is showed below. I mark the part which confuse me.
EXAMPLE_DIR = /user/$(USER)/matmult-dense/
INPUT_DIR = $(EXAMPLE_DIR)/input
OUTPUT_DIR = $(EXAMPLE_DIR)/output
OUTPUT_FILE = $(OUTPUT_DIR)/part-00000
HADOOP_VERSION = 2.6.0
# generally I use HADOOP_HOME, for not modifying the original makefile, I set up the HADOOP_PREFIX here
HADOOP_PREFIX = /usr/local/hadoop
TOOLLIBS_DIR=$(HADOOP_PREFIX)/share/hadoop/tools/lib/
//Hi, start here
run: inputs
hdfs dfs -rm -f -r $(EXAMPLE_DIR)
//Hi, end here. If swap them, the error comes

You seem to be badly confused about how makefiles work. You must start with simoke ones before you attempt complex ones.
If a makefile contains a rule like this:
foo: bar
kleb
then foo is a target (usually the name of a file that Make can build). bar is another target, and kleb is a command, which is to be executed by the shell. If you swap bar and kleb, you will probably get an error, because kleb is probably not a target that Make knows how to build, and bar is probably not a command the that the shell knows how to execute.
