[jira] Updated: (HIVE-93) dynamic serde does not handle '_' as the first character of a column name in a DDL

Ashish Thusoo updated HIVE-93:

    Component/s: Query Processor

I am not sure if this is a bug. All our identifiers are restricted to not start with _ so that we can handle the character set names. So any column name or table name beginning with an _ would lead to a parse error. Is that what you are getting? Can you upload the error string and then mark this as an improvement as opposed to a bug.
