import pyarrow as pa

client = pa.hdfs.connect('localhost', 9000)

错误

Traceback (most recent call last):
  File "/Users/wyx/project/py3.7aio/hdfs/list_dir.py", line 13, in <module>

pyarrow.lib.ArrowIOError: Unable to load libhdfs

我通过brew安装hadoop并获取任何本机库，因此我通过Native Libraries Guide构建hadoop3.1.1，但无法获取任何内容 libhdfs.so ，其中the pyarrow need我只得到 libhdfs.dylib
