java.lang.UnsatisfiedLinkError: org.apache.hadoop.io.nativeio.NativeIO Fails to start DFS

Question

I have installed/configured Hadoop on windows hadoop-2.6.0

I couldn't successfully start "sbin\start-dfs" run command.

I am getting below error

16/12/20 13:03:56 FATAL namenode.NameNode: Failed to start namenode.
java.lang.UnsatisfiedLinkError: org.apache.hadoop.io.nativeio.NativeIO$Windows.a

There was a similar question for running YARN. And it was told that including hadoop-2.6.0/sbin and hadoop-2.6.0/bin in path would resolve the problem. But still i am facing the error.

Can anyone help me in fixing this?

Please make sure you have proper access permission to namenode directory. Also, format the namenode and start the hdfs services.
