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.
