[jira] Commented: (PIG-1381) Need a way for Pig to take an alternative property file

["V.V.Chaitanya Krishna (JIRA)" <ji...@apache.org>]

V.V.Chaitanya Krishna commented on PIG-1381:
--------------------------------------------

bq. 2. Change the name for default pig.properties to pig-default.properties, and user can give a pig.properties to override
bq. 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.

 +1 to both the above approaches. In fact, I see that both are almost similar in the sense that user has the option to provide a set of properties in a file.

Since this is something that pig source-code provides, i think it makes sense to keep the filename (the one in which users can specify their own properties) fixed, rather than having it as a command line option.

Thoughts?

> 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.
