-----------------------------------------

             Summary: TableIdentifier.quotedString creates un-parseable names when name contains a backpack
                 Key: SPARK-17832
                 URL: https://issues.apache.org/jira/browse/SPARK-17832
             Project: Spark
          Issue Type: Bug
          Components: SQL
            Reporter: Herman van Hovell
            Priority: Minor


The {{quotedString}} method in {{TableIdentifier}} and {{FunctionIdentifier}} produce an illegal (un-parseable) name when the name contains a backtick. For example:
{noformat}
import org.apache.spark.sql.catalyst.parser.CatalystSqlParser._
import org.apache.spark.sql.catalyst.TableIdentifier
import org.apache.spark.sql.catalyst.analysis.UnresolvedAttribute
val complexName = TableIdentifier("`weird`table`name", Some("`d`b`1"))
parseTableIdentifier(complexName.unquotedString) // Does not work
parseTableIdentifier(complexName.quotedString) // Does not work
UnresolvedAttribute.parseAttributeName(complexName.unquotedString) // Does not work
UnresolvedAttribute.parseAttributeName(complexName.quotedString) // Does not work
{noformat}

The {{quotedString}} method should escape backticks properly.
