ERROR Shell: Failed to locate the winutils binary in the hadoop binary path

[saravananponnaiah]

With all the steps stated in https://github.com/dotnet/spark#get-started and when executing the command,
spark-submit --class org.apache.spark.deploy.DotnetRunner --master local microsoft-spark-2.4.x-0.1.0.jar HelloSpark
I am getting error message that states as below,

Could you please help finding what am I missing and resolve this issue.

I can able to access Spark shell using spark-shell command

Either ignore it or you can download winutils.exe put it a folder like c:\hadoop\bin then set HADOOP_HOME to c:\hadoop

Download from:

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

This is documented under "5. Install Apache Spark 2.3+" in (you need to click the "show console output" button:

https://github.com/dotnet/spark/blob/35048c9cfa324336497055d6543fa46b8d2de247/docs/building/windows-instructions.md

Awesome Eddie. It worked seamlessly. Thanks a lot for helping me out to run my first .Net Spark app... :-)
