Olga Natkovich updated PIG-1991:
--------------------------------
Fix Version/s: (was: 0.9.0)
Summary: Use of underscore in schema names (was: Use of leading
underscore(_) in schema names not allowed)
This is a new feature request which is too late for 0.9. We can consider it for
10 but in general we need to have strong reasons for changing Pig fundamentals
and this just does not strike me like something we need to change.
