Pyiceberg支持跨HDFS Cluster访问，用于访问线上iceberg表
现有的pyarrow模块根据catalog配置来初始化HadoopFileSystem,
```
catalog:
ice:
hdfs.host: xxxx
hdfs.port: xxx
```
如果实际访问的Cluster不是catalog配置的cluster，会触发Wrong FS异常
java.lang.IllegalArgumentException:
Wrong FS: hdfs://xxxx expected: hdfs://yyyy
改成优先采用制定的uri初始化，

The current pyarrow module creates FS from hdfs.host and hdfs.port in the catalog configuration.
However, when the real hdfs path has a anther netloc, it will throw Wrong FS execption.
