Subject [jira] Commented: (PIG-600) PiggyBank compilation instructions don't work
Date Mon, 22 Jun 2009 17:18:07 GMT

    [ https://issues.apache.org/jira/browse/PIG-600?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12722686#action_12722686
] 

Dmitriy V. Ryaboy commented on PIG-600:
---------------------------------------

Setting the CLASSPATH environment variable to include pig.jar is sufficient for building the
piggybank jar (and avoids the problem of having the whole pig directory checked out).
I've updated the Wiki.
This can be closed.

> I know that PiggyBank is "as-is" but the instructions are incomplete and should be complete
enough (all steps) required to compile PiggyBank.
> http://wiki.apache.org/pig/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:
> compile:
