             Summary: getColumnTypeName returns string for int partition columns
                 Key: HIVE-4775
                 URL: https://issues.apache.org/jira/browse/HIVE-4775
             Project: Hive
          Issue Type: Bug
          Components: JDBC
    Affects Versions: 0.9.0
            Reporter: Miklos Christine


For an 'int' partition column, the 'getColumnTypeName' metadata call is returning type 'string'. However, a DESCRIBE correctly returns type 'int'. 

Doug Sedlak mentioned this issue in a comment of Hive-2315.  https://issues.apache.org/jira/browse/HIVE-2315

A patch was submitted, but the ticket was closed before then. 

This appears to be a bug.
Similar issue here to address the consistency of the call:
https://issues.apache.org/jira/browse/HIVE-4519

Sample table is:
create EXTERNAL table partition_by_int (str_val string) PARTITIONED BY (int_col INT) ROW FORMAT delimited fields terminated by ',' STORED AS TEXTFILE;
And (shortened) JDBC code is:
res = stmt.executeQuery("select * from partition_by_int");
ResultSetMetaData metaData = res.getMetaData();
for (int i = 0; i < metaData.getColumnCount(); i++)
{ System.out.print(metaData.getColumnName(i + 1) + " \t"); System.out.print(metaData.getColumnDisplaySize(i + 1) + "\t"); System.out.println(metaData.getColumnTypeName(i + 1)); }
With output:
str_val 2147483647 string
int_col 2147483647 string
In contrast, DESCRIBE partition_by_int generates:
str_val string
int_col int
