>             Project: Hive
>          Issue Type: Bug
>    Affects Versions: 0.13.1
>            Reporter: Sergio Peña

> Look at the following code:
> {noformat}
> Class.forName("org.apache.hive.jdbc.HiveDriver");
>         Connection db = null;
>         Statement stmt = null;
>         ResultSet rs = null;
>         try {
>             db = DriverManager.getConnection("jdbc:hive2://localhost:10000/default",
"hive", "");
>             stmt = db.createStatement();
>             rs = stmt.executeQuery("SELECT * FROM sample_07 limit 1");
>             ResultSetMetaData metaData = rs.getMetaData();
>             for (int i = 1; i <= metaData.getColumnCount(); i++) {
>                 System.out.println("Column " + i + ": " + metaData.getColumnName(i));
>             }
>             while (rs.next()) {
>                 System.out.println(rs.findColumn("code"));
>             }
>         } finally {
>             DbUtils.closeQuietly(db, stmt, rs);
>         }
> {noformat}
> Above program will generate following result on my cluster:
> {noformat}
> Column 1: code
> Column 2: description
> Column 3: total_emp
> Column 4: salary
> 1
> {noformat}
> However, if the last print sentence is changed as following (using uppercase characters):
> {noformat}
> System.out.println(rs.findColumn("Code"));
> {noformat}
> The program will fail at exactly that line. The same happens if the column name is changed
as "CODE"
> Based on the JDBC ResultSet documentation, this method should be case insensitive.
> "Column names used as input to getter methods are case insensitive"
> http://docs.oracle.com/javase/7/docs/api/java/sql/ResultSet.html
