Subject [jira] Created: (PIG-1618) Switch to new parser generator technology

Switch to new parser generator technology

                 Key: PIG-1618
                 URL: https://issues.apache.org/jira/browse/PIG-1618
             Project: Pig
          Issue Type: Bug
    Affects Versions: 0.8.0
            Reporter: Alan Gates
            Assignee: Xuefu Zhang
             Fix For: 0.9.0

There are many bugs in Pig related to the parser, particularly to bad error messages.  After
review of Java CC we feel these will be difficult to address using that tool.  Also, the .jjt
files used by JavaCC are hard to understand and maintain.  

ANTLR is being reviewed as the most likely choice to move to, but other parsers will be reviewed
as well.

This JIRA will act as an umbrella issue for other parser issues.
