Exception in thread "main" java.lang.UnsatisfiedLinkError: org.apache.hadoop.io.nativeio.NativeIO$Windows.access0(Ljava/lang/String;I)Z

Solution 1:

In addition to other solutions, Please download winutil.exe and hadoop.dll and add to $HADOOP_HOME/bin. It works for me.

https://github.com/steveloughran/winutils/tree/master/hadoop-2.7.1/bin

Note: I'm using hadoop-2.7.3 version enter image description here

Solution 2:

After putting haddop.dll and winutils in hadoop/bin folder and adding the folder of hadoop to PATH, we also need to put hadoop.dll into the C:\Windows\System32 folder

Solution 3:

This issue occurred to me and the cause was I forgot to append %HADOOP_HOME%/bin to PATH in my environment variables.

Solution 4:

For me this issue was resolved by downloading the winutils.exe & hadoop.dll from https://github.com/steveloughran/winutils/tree/master/hadoop-2.7.1/bin and putting those in hadoop/bin folder

Solution 5:

After trying all the above, things worked after putting hadoop.dll to windows/System32
