If by "using", you mean distributing it, then you can use Distributed Cache to do this. Like this:

DistributedCache.addFileToClassPath(new Path("file:///path_to_your_file"), job);

You can find more about Distributed Cache here:

https://hadoop.apache.org/docs/current/api/org/apache/hadoop/filecache/DistributedCache.html
