This seems to be a good link to start

Tutorial at this link demonstrates how you can create and run MapReduce sample project with Eclipse IDE. It does not discuss details of actual code. For that you should visit official Apache Hadoop website

Not satisfctory

The above assumes you have installed hadoop. I am looking to see how I can just compile the job first without installing hadoop. I may chose to run it on aws. I just want to compile it.

I am perhaps looking for a root group and jar files for hadoop on Artefactory

Here is that question on SOF

satya - 3/16/2019, 4:50:15 PM

wonder if this set works


// https://mvnrepository.com/artifact/org.apache.hadoop/hadoop-core
compile group: 'org.apache.hadoop', name: 'hadoop-core', version: '1.2.1'

But the dependencies for this jar are very large

This is assuming I need the entire jar set!!!

All I need is to compile a map reduce!!

wonder if there is a smaller subset

They seem to suggest hadoop 1.2.1 core! I guess give it a shot

The configuration object contains all Hadoop settings necessary to launch your app. It's in key value format and is read from the xml files from /etc/hadoop. You can also use Configuration to change configuration parameters.

Is it possible to run MapReduce locally, without HDFS and Hadoop cluster?
