Description

Currently, we can specify a log4j.properties file to Pig command line like so

pig -4 /path/to/log4j.properties

It will be quite helpful if it read the log4j.properties from the classpath as well.
For instance in the same command we can specify...

pig -4 log4j.properties

And Pig can first try to read it as a file and failing that could try reading it from the classpath, similar to how log4j handles the property - log4j.configuration.

We needed this as one of your projects contained the log4j.properties file embedded inside the project jar

I've attached a simple patch with a testcase to that effect.
