Getting a error while using code "hadoop fs -mkdir /in"

While installing hadoop in windows 8.1 pro and was ready to run mapreduce I got this error message.

Unable to make directory and further more errors are mentioned below.


-mkdir: java.net.URISyntaxException: Illegal character in hostname at index 24:
hdfs://localhost127.0.0.1:9000
Usage: hadoop fs [generic options] -mkdir [-p] <path> ...

for this command
hadoop fs -copyFromLocal c:\Hwork\recipeitems-latest.json /in
I'm getting something like this

-copyFromLocal: java.net.URISyntaxException: Illegal character in hostname at in
dex 24: hdfs://localhost127.0.0.1:9000
Usage: hadoop fs [generic options] -copyFromLocal [-f] [-p] <localsrc> ... <dst>


please help me to get rid of it
