如何在pywebhfds中传递连接错误？

from hdfs import InsecureClient

def connect_to_hdfs(host, port, user):
    try:
        client = InsecureClient(f"http://{host}:{port}", user=user)
        print("Successfully connected to HDFS")
        return client
    except Exception as e:
        print("Failed to connect to HDFS. Connection Error: ", e)
        return None

# 用适当的参数替换下面的值
host = "your_hdfs_host"
port = "your_hdfs_port"
user = "your_username"

client = connect_to_hdfs(host, port, user)

if client is not None:
    # 在此处执行与HDFS相关的操作，例如读取、写入等
else:
    print("Unable to perform HDFS operations due to connection error.")
