[jira] [Commented] (PIG-1429) Add Boolean Data Type to Pig

["Zhijie Shen (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/PIG-1429?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13066358#comment-13066358 ] 

Zhijie Shen commented on PIG-1429:
----------------------------------

Does anyone have the opinion of casting DataByteArray to Boolean?

1. DataByteArray can represent a numeric value, such that non-zero value should be converted to True.
2. DataByteArray can also represent a string, such that the "true" string should be converted to True.

However, these two cases conflicts to some extent. a raw DataByteArray can be simultaneously translated into a non-zero numeric or a non-"true" string. Then, it is hard to say whether it should be converted to True or False.

> Pig needs a Boolean data type.  Pig-1097 is dependent on doing this.  
> I volunteer.  Is there anything beyond the work in src/org/apache/pig/data/ plus unit tests to make this work?  
> This is a candidate project for Google summer of code 2011. More information about the program can be found at http://wiki.apache.org/pig/GSoc2011
