Qi Chen 124516c1ea [Fix](orc-reader) Fix Wrong data type for column error when column order in hive table is not same in orc file schema. (#21306 )

`Wrong data type for column` error when column order in hive table is not same in orc file schema.

The root cause is in order to handle the following case:

The table in orc format of Hive 1.x may encounter system column names such as `_col0`, `_col1`, `_col2`... in the underlying orc file schema, which need to use the column names in the hive table for mapping.

### Solution
Currently fix this issue by handling the following case by specifying hive version to 1.x.x in the hive catalog configuration.

```sql
CREATE CATALOG hive PROPERTIES (
    'hive.version' = '1.x.x'
);
```

Doris Develop Environment based on docker

Preparation

Download the Doris code repo
```
$ cd /to/your/workspace/
$ git clone https://github.com/apache/doris.git
$ cd doris
$ git submodule update --init --recursive
```
You can remove the .git dir in doris/ to make the dir size smaller. So that the following generated docker image can be smaller.

Copy Dockerfile

$ cd /to/your/workspace/
$ cp doris/docker/Dockerfile ./

After preparation, your workspace should like this:

.
├── Dockerfile
├── doris
│   ├── be
│   ├── bin
│   ├── build.sh
│   ├── conf
│   ├── DISCLAIMER-WIP
│   ├── docker
│   ├── docs
│   ├── env.sh
│   ├── fe
│   ├── ...

Build docker image

$ cd /to/your/workspace/
$ docker build -t doris:v1.0  .

doris is docker image repository name and v1.0 is tag name, you can change them to whatever you like.

Use docker image

This docker image you just built does not contain Doris source code repo. You need to download it first and map it to the container. (You can just use the one you used to build this image before)

$ docker run -it -v /your/local/path/doris/:/root/doris/ doris:v1.0
$ docker run -it -v /your/local/.m2:/root/.m2 -v /your/local/doris-DORIS-x.x.x-release/:/root/doris-DORIS-x.x.x-release/ doris:v1.0

Then you can build source code inside the container.

$ cd /root/doris/
$ sh build.sh

NOTICE

The default JDK version is openjdk 11, if you want to use openjdk 8, you can run the command:

$ alternatives --set java java-1.8.0-openjdk.x86_64
$ alternatives --set javac java-1.8.0-openjdk.x86_64
$ export JAVA_HOME=/usr/lib/jvm/java-1.8.0

The version of jdk you used to run FE must be the same version you used to compile FE.
