I have been following this article regarding installing Hadoop and I have completed the article.

However, upon trying to make a new hdfs folder, the following error occured. 

C:\hadoop-2.8.0\bin>hadoop fs -mkdir /user/input
WARNING: An illegal reflective access operation has occurred
WARNING: Illegal reflective access by org.apache.hadoop.security.authentication.util.KerberosUtil (file:/C:/hadoop-2.8.0/share/hadoop/common/lib/hadoop-auth-2.8.0.jar) to method sun.security.krb5.Config.getInstance()
WARNING: Please consider reporting this to the maintainers of org.apache.hadoop.security.authentication.util.KerberosUtil
WARNING: Use --illegal-access=warn to enable warnings of further illegal reflective access operations
WARNING: All illegal access operations will be denied in a future release
mkdir: `/user/input': No such file or directory

This stumps me because I am trying to make a folder, not executing a -ls or -put command.

For the record, I am on Windows 10 on a command prompt that is run as administrator.

Check whether all services are up and running namenode, datanode etc.... using jps command as shown in the reference.

Also, Try configuring to Java8.
