It seems that all of the examples are constructed with older versions in mind.

How do I compile my java program on Ubuntu such that it will refer to hadoop-2.2.0 libraries?

Where are the jar files that I am supposed to include?

What is the command? Is it like -

javac -classpath libraries wordcount.java

Answer 1

The simplest solution for Linux machines would be:

javac -classpath `yarn classpath` -d . WordCount.java

Or:

export CLASSPATH=`yarn classpath`
javac -classpath $CLASSPATH -d . WordCount.java
