How to use jar file without putting it in hdfs

Question

I have a jar file in my local system and I want to use it without actually putting in the hdfs. How can I do that?

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:
