How to include my own jar when building Hadoop?

I modified Hadoop source code. I need to include my own jar. Where
should I put the jar? Do I need to change Hadoop config file?

If you've modified Hadoop sources, you can use it's ant build-system's
"jar" command to make a jar for you with your changes compiled into
it. You can then use that created jar (from build/) to deploy it.

Hi,

I think you can put it into $HADOO_HOME/lib
