我一直在尝试通过pip安装pyarrow( pip install pyarrow ，并且，正如雅加夫所建议的： py -3.7 -m pip install --user pyarrow )还有康达( conda install -c conda-forge pyarrow ，也用于 conda install pyarrow )，从src构建lib（使用conda环境和一些魔术，我不太了解），但是一直以来，在安装之后（没有错误），它以一个相同的问题结束，当我调用：

import pyarrow as pa
fs = pa.hdfs.connect(host='my_host', user='my_user@my_host', kerb_ticket='path_to_kerb_ticket')

它将失败，并显示下一条消息：

一开始我在想，hadoop2.5.6中的libhdfs.so有一个问题，但似乎我错了。我猜，问题不在pyarrow或子流程中，而是一些系统变量或依赖项。
我还手动定义了系统变量 HADOOP_HOME , JAVA_HOME 以及 KRB5CCNAME
