Adam Szita commented on PIG-4934:
---------------------------------
We could create a util function for this that acts as getAlternateNames and
returns an enriched set of properties from a single key-value pair. See
[^PIG-4934.patch] as example (without error-handling and testing just yet)
> SET command does not work well with deprecated settings

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