Small note --bug solve: Idea running locally Spark job, missing winutils.exe hadoop.dll file

1. The problem scenario:

• window environment, using the idea Spark job development, job and run the job, an error

2. solve the problem:

• The cause of the problem: window environment is not compatible with reason, file deletion winutils.exe hadoop.dll
• Download Path: https://github.com/steveloughran/winutils
• The downloaded file into hadoop / bin (Note: You have to configure the system environment variable) directory, and copy hadoop.dll to the window / system32 / directory
• Restart the computer or idea
