ElasticSearch 错误：“客户端注意到服务器不是 Elasticsearch 支持的发行版”

Question

ElasticSearch 新手。我按照本指南进行设置：https ://john.soban.ski/boto3-ec2-to-amazon-elasticsearch.html

我在那里运行了“connect_to_es.py”脚本，奇怪的是它第一次工作，但在随后的运行中，它开始抛出此错误：

Traceback (most recent call last):
  File "../connect_to_es.py", line 21, in <module>
    print(json.dumps(es.info(), indent=4, sort_keys=True))
  File "/home/ubuntu/projects/.venv/lib/python3.8/site-packages/elasticsearch/client/utils.py", line 168, in _wrapped
    return func(*args, params=params, headers=headers, **kwargs)
  File "/home/ubuntu/projects/.venv/lib/python3.8/site-packages/elasticsearch/client/__init__.py", line 294, in info
    return self.transport.perform_request(
  File "/home/ubuntu/projects/.venv/lib/python3.8/site-packages/elasticsearch/transport.py", line 413, in perform_request
    _ProductChecker.raise_error(self._verified_elasticsearch)
  File "/home/ubuntu/projects/.venv/lib/python3.8/site-packages/elasticsearch/transport.py", line 630, in raise_error
    raise UnsupportedProductError(message)
elasticsearch.exceptions.UnsupportedProductError: The client noticed that the server is not a supported distribution of Elasticsearch

我的elasticsearch python库版本是7.14，我在AWS上的elasticsearch运行的是7.10。对这里发生的事情有什么想法吗？

代码副本：

from elasticsearch import Elasticsearch, RequestsHttpConnection
from requests_aws4auth import AWS4Auth
import boto3
import json

host = '<url>.us-east-1.es.amazonaws.com'
region = 'us-east-1'

service = 'es'
credentials = boto3.Session().get_credentials()
awsauth = AWS4Auth(credentials.access_key, credentials.secret_key, region, service, session_token=credentials.token)

es = Elasticsearch(
    hosts = [{'host': host, 'port': 443}],
    http_auth = awsauth,
    use_ssl = True,
    verify_certs = True,
    connection_class = RequestsHttpConnection
)

print(json.dumps(es.info(), indent=4, sort_keys=True))

Answer 1

似乎降级修复了它pip3 install 'elasticsearch<7.14.0'

Answer 2

新elasticsearch-js的有一个问题：

• 新产品版本检查拒绝oss发行版？

将其降级到较低版本（例如 7.13）应该会有所帮助。
