我可以使用python的看门狗监视HDFS目录中的更改吗？如果没有，如何使用Python做到这一点？ （我发现的所有内容都是使用Java编写的）

Question

我想使用python（我发现的所有内容都在java中）收听HDFS中的特定目录。 当文件上传或移动到受监视的目录时，我希望我的python脚本对其执行不同的操作，然后删除该目录中的所有文件。问题是，我找不到使用python监视HDFS中的目录的方法。

我尝试使用看门狗，如您在所附代码中看到的那样，但它无法解析路径。路径存在并且目录也存在，但我显示错误：路径不是目录。 在此处输入代码

from hdfs import InsecureClient

client_hdfs = InsecureClient('', user='')

TestWatcher = client_hdfs.resolve("")

print(TestWatcher)

import time  
from watchdog.observers import Observer
#from watchdog.observers.polling import PollingObserver
from watchdog.events import PatternMatchingEventHandler  

if __name__ == "__main__":
    #patterns = "*"
    patterns = "*.pickle"
    ignore_patterns = ""
    ignore_directories = False
    case_sensitive = True
    #case_sensitive = False
    my_event_handler = PatternMatchingEventHandler(patterns, 
    ignore_patterns, ignore_directories, case_sensitive)

def on_created(event):
    print(f"hey, {event.src_path} has been created!")

def on_deleted(event):
    print(f"what the f**k! Someone deleted {event.src_path}!")

def on_modified(event):
    print(f"hey buddy, {event.src_path} has been modified")

def on_moved(event):
    print(f"ok ok ok, someone moved {event.src_path} to 
    {event.dest_path}")

my_event_handler.on_created = on_created
my_event_handler.on_deleted = on_deleted
my_event_handler.on_modified = on_modified
my_event_handler.on_moved = on_moved

path = TestWatcher
go_recursively = False
my_observer = Observer()
#my_observer = PollingObserver()

my_observer.schedule(my_event_handler, path, recursive=go_recursively)

my_observer.start()
try:
    while True:
        time.sleep(1)
except KeyboardInterrupt:
    my_observer.stop()
my_observer.join()

错误OS错误：路径不是目录
