[jira] [Resolved] (PIG-1991) Leading Underscore (_) not allowed in
schema names
[ https://issues.apache.org/jira/browse/PIG-1991?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Alan Gates resolved PIG-1991.
-----------------------------
Resolution: Won't Fix
The definition of variable names for Pig is:
[a-zA-Z][a-zA-Z0-9]*
I don't see any compelling reason to change that.
