I am a beginner to Hadoop MapReduce.
I have implemented a MapReduce job in visual C# and want to run it locally. As I understood, the HDInsight emulator hasn't been updated for a long time. What else options I have, to run the job locally?

In general Hadoop Mapreduce job can be run in below three modes:
- MR Job can be run in standalone mode - where everything runs in a single JVM or Process.
mapreduce.framework.namehas to be set tolocal
https://blogs.justenougharchitecture.com/apache-hadoop/ - One Node Hadoop cluster can be setup on the Work Machine and the job can be submitted into it.
Related article - https://www.edureka.co/blog/install-hadoop-single-node-hadoop-cluster - The job can be submitted from Work Machine into the Remote Running Hadoop Cluster.
Related doc - https://learn.microsoft.com/en-us/azure/hdinsight/hadoop/apache-hadoop-dotnet-csharp-mapreduce-streaming
Do let us know if you have further questions or please elaborate your requirement so that we can assist accordingly.

2022-02-25T20:30:24.82+00:00 Thank you very much replying. Actually, I setup a single-node Hadoop cluster but as I understood you need to write your MapReduce job in Java to run on it.
But I implemented in Visual C# and installed Microsoft .NET MapReduce API for Hadoop in Visual studio as described in https://www.youtube.com/watch?v=uyi41nrhlhw.However to run it, I cannot install windows HDInsight emulator. Therefore, need to know other options available to run my MapReduce job written in C#.
