回答1:

You are missing winutils.exe, a hadoop binary. Depending upon x64 bit / x32 bit system, download the winutils.exe file & set your hadoop home pointing to it.

1st way :

1.Download the file

2.Create hadoop folder in Your System ex " C:"

3.Create bin folder in hadoop directory ex : C:\hadoop\bin

4.paste winutils.exe in bin ex: C:\hadoop\bin\winuitls.exe

5.In User Variables in System Properties -> Advance System Settings

Create New Variable Name: HADOOP_HOME Path: C:\hadoop\

2nd Way :

You can set hadoop home directly in Your Java Program with the following Command like this :

System.setProperty("hadoop.home.dir","C:\hadoop" );
