java - 获取 org.apache.hadoop.hive.ql.exec.vector.DecimalColumnVector 无法转换为 org.apache.hadoop.hive.ql.exec.vector.LongColumnVector

Question

// column: bigint
          if (getTypes(column, struct).equalsIgnoreCase("bigint")) {
            if (!lineArray[column].isEmpty()) {
                try {
                    ((LongColumnVector) batch.cols[column]).vector[row] = Long.parseLong(lineArray[column]);
                } catch (NumberFormatException e) {
                    HiveDecimal hiveDecimal = HiveDecimal.create(lineArray[column]);
                    batch.cols[column]=new DecimalColumnVector(lineArray[column].length(), 0);
                    ((DecimalColumnVector) batch.cols[column]).vector[row] = (new HiveDecimalWritable(hiveDecimal));
                } catch (Exception e) {
                    e.printStackTrace();
                }
                } else {
                       ((LongColumnVector) batch.cols[column]).noNulls = false;
                       ((LongColumnVector) batch.cols[column]).isNull[row] = true;
                       ((LongColumnVector) batch.cols[column]).vector[row] = LongColumnVector.NULL_VALUE;
                       // ((CustomLongColumnVector) batch.cols[column]).fillWithNulls();
                }

          }

我正在尝试执行上面的代码片段。lineArray是一个字符串数组。但它失败了java.lang.ClassCastException: org.apache.hadoop.hive.ql.exec.vector.DecimalColumnVector cannot be cast to org.apache.hadoop.hive.ql.exec.vector.LongColumnVector。请帮忙。
