Hello All,

I have a 3 node elastic cluster setup on EC2. I am trying to connect to my cluster and index some sample data using python script.

Below is my python script: -

`````auto
from elasticsearch import Elasticsearch
es=Elasticsearch([{'host':'http://(xx.xxx.xxx.xxx):9200','port':9200,'scheme':"http"}])
print es

e1={
    "first_name":"nitin",
    "last_name":"panwar",
    "age": 27,
    "about": "Love to play cricket",
    "interests": ['sports','music'],
}

print e1

#storing e1 document in Elasticsearch
res = es.index(index='ep1',doc_type='employee',id=1,body=e1)
print res

I am executing the above python script on one of the EC2 which is part of Elasticsearch cluster.
But while executing the above script i am getting below error

<Elasticsearch([{'host': 'http://xx.xxx.xxx.xxx:9200', 'scheme': 'http', 'port': 9200}])>
{'interests': ['sports', 'music'], 'about': 'Love to play cricket', 'first_name': 'nitin', 'last_name': 'panwar', 'age': 27}
Traceback (most recent call last):

Please reformat your post, your use of code formatting for the entire thing makes the non-code sections very difficult to follow.

The `host` parameter when you create the client seems to contain a full URL rather than a host name. Can you try replacing this with just the hostname or ip address?

It worked by putting only ip as a host name. Thanks Christian
