             Summary: Support wider range of characters in Impala identifiers
                 Key: IMPALA-6152
                 URL: https://issues.apache.org/jira/browse/IMPALA-6152
             Project: IMPALA
          Issue Type: Improvement
            Reporter: Matyas Orhidi
            Priority: Normal


Currently the following characters are available in Impala identifiers: 

{quote}An identifier must start with an alphabetic character. The remainder can contain any combination of alphanumeric characters and underscores. Quoting the identifier with backticks has no effect on the allowed characters in the name.{quote} 

Some data migration use cases would require a wider range of characters. Also the following fails in Impala due to '+' in the column but works in hive 

{code}impala-shell> create table asd (`foo+bar` int); 
Query: create table asd (`foo+bar` int) 
ERROR: AnalysisException: Invalid column/field name: foo+bar{code}
