-Re: [pig-0.10.0]: what jar are included in pig-0.10.0.jar and pig-0.10.0-withouthadoop.jar?
As far as I know pig-0.10.0-withouthadoop.jar is generally used when you
want to use your own distribution of hadoop to use with PIG. Having said
that, yes it won't include any hadoop dependencies. If you want to use
hadoop jar files from a external hadoop package, just use
pig-0.10.0-withouthadoop.jar, and put hadoop jar files and hadoop
dependencies in pig classpath, this is how I am doing it.
Also put pig-0.10.0-wihouthadoop.jar in HADOOP_CLASSPATH also, just to be
in safe side (although its not required).
