[jira] [Created] (PIG-1991) Use of underscore in schema names
Use of underscore in schema names
---------------------------------
Key: PIG-1991
URL: https://issues.apache.org/jira/browse/PIG-1991
Project: Pig
Issue Type: Wish
Components: grunt
Affects Versions: 0.9.0
Reporter: Viraj Bhat
Fix For: 0.9.0
I have a Pig script which uses underscore in its schema name (_a)
{code}
a = load 'test.txt' as (_a:long, b:chararray);
dump a;
{code}
This causes an error in Pig:
{quote}
<line 1, column 24> Unexpected character '_'
2011-04-12 11:58:59,624 [main] ERROR org.apache.pig.tools.grunt.Grunt - ERROR 1200: <line 1, column 24> Unexpected character '_'
{quote}
Stack trace:

[jira] [Resolved] (PIG-1991) Leading Underscore (_) not allowed in
schema names
Posted by "Alan Gates (JIRA)" <ji...@apache.org>.
[ 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.

--------------------------------
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.
