Subject [jira] Commented: (PIG-600) PiggyBank compilation instructions don't work
Date Wed, 07 Jan 2009 17:16:46 GMT

    [ https://issues.apache.org/jira/browse/PIG-600?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12661641#action_12661641
] 

David Ciemiewicz commented on PIG-600:
--------------------------------------

I think the problem is this ... the build.xml file is looking for pig.jar several directories
up:

    <property name="pigjar" value="../../../pig.jar" />

The thing is, I'm relying on another build of pig and not the whole pig directory.

If you take the instructions for PiggyBank literally (as I did) you will not get a successful
build.

> I know that PiggyBank is "as-is" but the instructions are incomplete and should be complete
enough (all steps) required to compile PiggyBank.

> I checked out the types branch version of PiggyBank by modifying the instructions to
check out:
> svn co http://svn.apache.org/repos/asf/hadoop/pig/branches/types/contrib/piggybank/
> At step 2 it says:
> To build a jar file that contains all available user defined functions (UDFs), please
follow the steps:
> 1. Checkout UDF code: svn co http://svn.apache.org/repos/asf/hadoop/pig/trunk/contrib/piggybank
> 2. Build the jar file: from trunk/contrib/piggybank/java directory run ant. This will
generate piggybank.jar in the same directory.
> So I went into the piggybank/java directory and and ran ant and got the following errors:
> {code}
> -bash-3.00$ ant
> Buildfile: build.xml
> init:
