> I have a table age_group and I am trying to get list of columns for this
> table name. As underscore and '%' have special meaning in table search
> pattern according to JDBC searchPattern string specification, I escape the
> '_' in my table name when I call getColumns for this single table. But HIVE
> does not return any columns. My call to getColumns is as follows
> catalog <null>
> schemaPattern "%"
> tableNamePattern "age\_group"
> columnNamePattern "%"
> If I don't escape the '_' in my tableNamePattern, I am able to get the list
> of columns.
