Description

For eg: If mapred.job.map.memory.mb was specified in the script using set command and mapreduce.map.memory.mb was present in mapred-site.xml, that takes effect. This is because of the use of Properties and not Configuration.

GruntParser.processSet() calls HExecutionEngine.setProperty which just updates pigContext.getProperties()

public void setProperty(String property, String value) {
        Properties properties = pigContext.getProperties();
        properties.put(property, value);
    }
