> Hive decimal type column precision is returning as zero, even though column has precision
set.
> Example: col67 decimal(18,2) precison is returning as zero for that column.
> Tried with below program.
>    System.out.println("Opening connection");   Class.forName("org.apache.hive.jdbc.HiveDriver");
>         System.out.println("hi");
>    Connection con = DriverManager.getConnection("jdbc:hive2://x.x.x.x:10000/default");
>   DatabaseMetaData dbMeta = con.getMetaData();
>    ResultSet rs = dbMeta.getColumns(null, "DEFAULT", "data_type_test",null);
>  while (rs.next()) {
> if (rs.getString("COLUMN_NAME").equalsIgnoreCase("col48") || rs.getString("COLUMN_NAME").equalsIgnoreCase("col67")
|| rs.getString("COLUMN_NAME").equalsIgnoreCase("col68") || rs.getString("COLUMN_NAME").equalsIgnoreCase("col122")){
>      System.out.println(rs.getString("COLUMN_NAME") + "\t" + rs.getString("COLUMN_SIZE")
+ "\t" + rs.getInt("DECIMAL_DIGITS"));
>     }
>    }
>    rs.close();
>    con.close();
>   } catch (Exception e) {
>    e.printStackTrace();
>    ;
>   }
> Default fetch size is 50. if any column no is under 50 with decimal type precision is
returning properly, when the column no is greater than 50, precision is returning as zero.
