V.V.Chaitanya Krishna commented on PIG-1381:
--------------------------------------------
bq. I think key=value is easier for people to understand.
Yes. I think it is a valid way of putting up properties. But I think xml
format gives more structured-ness to the properties file, no? But however, this
would also mean a significant code change in terms of the approach for loading
the properties (things like xml parsing etc. might have to be taken care of).
bq. For option 2 I think we'd need to provide an empty pig.properties file
(just as hadoop provides an empty hadoop-site.xml).
We can provide the current pig.properties file itself, with the default
values. So it would be somewhat analogous to hadoop-default.xml. I would also
propose that this be bundled in the jar itself and thus avoid it to be changed
by users. (because they would have a different properties file already to put
up their settings).
Thoughts?

> Key: PIG-1381
> URL: https://issues.apache.org/jira/browse/PIG-1381
> Project: Pig
> Issue Type: Improvement
> Components: impl
> Affects Versions: 0.7.0
> Reporter: Daniel Dai
> Fix For: 0.8.0
>
>
> Currently, Pig read the first ever pig.properties in CLASSPATH. Pig has a
> default pig.properties and if user have a different pig.properties, there
> will be a conflict since we can only read one. There are couple of ways to
> solve it:
> 1. Give a command line option for user to pass an additional property file
> 2. Change the name for default pig.properties to pig-default.properties, and
> user can give a pig.properties to override
> 3. Further, can we consider to use pig-default.xml/pig-site.xml, which seems
> to be more natural for hadoop community. If so, we shall provide backward
> compatibility to also read pig.properties, pig-cluster-hadoop-site.xml.
