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

If we decide to treat bytes as string and then convert to a boolean value, we 
should convert a boolean value to the bytes of "true" and "false" on the other 
way. Otherwise, the casting is not reversible. Do you agree this? Though the 
boolean storage seems not efficient.

> 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
