    How can we compile and execute map reduce programs without using eclipse?

    1) Write your MapReduce Program in a Text editor of your choice.

    2) Place the source code (.java) file in any folder.

    3) Compile the source using the following command:
    javac -cp <path to hadoop client libraries> -d classes *.java

    4) Create a jar file:
    jar cvf sample.jar classes

    5) Execute the jar file
    hadoop jar sample.jar <fully qualified main class> <arg1> <arg2> ...

    Alternatively, if you have Maven installed, then you can do the same by creating a Maven Project Structure from the Command Line, create a pom.xml and executemvn packagewithout worrying about external client libraries that Apache provides for Hadoop.
