Examples of org.apache.pig.scripting.ScriptEngine.run()

org.apache.pig.scripting.ScriptEngine.run()
Runs a script file. @param pigContext {@link PigContext} to run the script file @param scriptFile the file @return a collection of {@link PigStats} objects. One for each runtime instance of {@link Pig} in the script. For named pipelines, themap key is the name of the pipeline. For unnamed pipeline, the map key is the script id associated with the instance. @throws ExecException @throws IOException
