Ambari代理分发/配置选择版本有以下几个解决方法，其中包含了代码示例：

1. 使用Ambari REST API进行版本选择：

import requests

def select_version(ambari_url, cluster_name, service_name, component_name, version):
    url = f"{ambari_url}/api/v1/clusters/{cluster_name}/services/{service_name}/components/{component_name}"
    headers = {"X-Requested-By": "ambari"}
    params = {"ServiceComponentInfo": {"desired_stack_id": version}}
    response = requests.put(url, headers=headers, json=params)
    
    if response.status_code == 200:
        print("Version selection successful")
    else:
        print("Version selection failed")

# Example usage
ambari_url = "http://localhost:8080"
cluster_name = "my_cluster"
service_name = "HDFS"
component_name = "DATANODE"
version = "HDP-3.1.0.0"

select_version(ambari_url, cluster_name, service_name, component_name, version)

2. 使用Ambari Python库进行版本选择：

from ambari_client import AmbariClient

def select_version(ambari_url, username, password, cluster_name, service_name, component_name, version):
    client = AmbariClient(ambari_url, username, password)
    client.select_version(cluster_name, service_name, component_name, version)

# Example usage
ambari_url = "http://localhost:8080"
username = "admin"
password = "admin"
cluster_name = "my_cluster"
service_name = "HDFS"
component_name = "DATANODE"
version = "HDP-3.1.0.0"

select_version(ambari_url, username, password, cluster_name, service_name, component_name, version)

这两种方法都可以通过指定Ambari的URL、用户名、密码、集群名、服务名、组件名和版本号来选择特定的版本。请根据你的实际情况选择适合的方法。
