Subject [jira] Commented: (PIG-1381) Need a way for Pig to take an alternative property file
Date Fri, 30 Apr 2010 17:32:54 GMT

    [ https://issues.apache.org/jira/browse/PIG-1381?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12862758#action_12862758
] 

Daniel Dai commented on PIG-1381:
---------------------------------

We have an internal discussion and decide to take option 1. In the command line, we take -propertyfile
<name> for the alternative property file name. Pig will first load pig.properties, and
then load alternative property file in classpath. Later entry will overwrite the previous
seen one, ie. alternative property file will take precedence over pig.properties.

> 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.
