  my_int INT,
  my_decimal DECIMAL(38,12)
) STORED AS ORC;

INSERT INTO my_table2 (my_int, my_decimal)
VALUES (123,10.123456789876);

2. Create Doris table and import data:

CREATE TABLE my_table2 (
  my_int INT,
  my_decimal DECIMALV3(38,12)
) 
DISTRIBUTED BY HASH(`my_int`) BUCKETS 1 
PROPERTIES (
"replication_allocation" = "tag.location.default: 1");

3. Load hive orc files to Doris table by broker loader.

LOAD LABEL deciamlv3test
    (
        DATA INFILE("hdfs://172.16.10.13:4007/usr/hive/warehouse/lqftest.db/my_table2/*")
        INTO TABLE my_table2
        FORMAT AS "orc"
    )
WITH BROKER 'broker'
    (
        "username" = "hadoop",
        "password" = "" 
    )
PROPERTIES
