I am using elasticsearch oss but now shifting towards open distro for elasticsearch. I have installed and configure kibana. but i am confuse about ingestion data to elasticsearch using python client libraries.
Can we use Python Elasticsearch Client or elasticsearch dsl library with open distro version.?
If not then what would be the alternation solution for writing python scripts with open distro version?
I did not do any big implementation in Python but I did with the official PERL Elasticsearch Client. It worked for me (both ODFE 1.10 and 1.12) without an issue . I assume it will work for any client as long as you don’t use any X-PACK features.
I really don’t know - you need to try and see how it works. I have different roles and users in Opendistro security plug-in and the user which connects and activates Elasticsearch APIs is a user which was defined with the permissions set similar to built-in user admin and as I said, it worked smoothly. When I tried to activate the same process which connects and deletes old indices based on age/size criteria with user which does not have the respective permissions, the connect method immediately failed with HTTP403, so, it really works as expected. My gut feeling - it will work for you but of course you need to test it.
I’m not aware of any problems with the client libraries on Open Distro. From the perspective of your client library, it’s sending HTTP requests with Query DSL payloads to the server.
If you’re running DSL queries that are specific to security (e.g. updating role, permissions, or something similar) then yes, those would have a different set of DSL queries. You can read more about this in our docs. But for normal ingest this isn’t an issue.
As @igorid70 mentions, you’ll have to try it out, but I doubt you’ll have issues. If you do, just come back here and perhaps we can help you.
Open distro for elasticsearch has its own security plugin. so due to that we have some default settings for this plugin included in elasticsearch.yml… To establish successful connection with elasticsearch server we need to provide basic authentication credentials(admin:admin). If we are using Python Elasticsearch Client for establishing connection with elasticsearch server(open distro version)will not work(Protocol not found error). So do we need to disable security plugin for using python library?
Thank you very much for your efforts.I could not make it work.
I am using RPM package of ODFE. I am running my scripts from remote machine. I tried as per your suggestion. elasticsearch.exceptions.ConnectionError: ConnectionError(<urllib3.connection.HTTPSConnection object at 0x7f3d0734c198>: Failed to establish a new connection: [Errno -2] Name or service not known) caused by: NewConnectionError(<urllib3.connection.HTTPSConnection object at 0x7f3d0734c198>: Failed to establish a new connection: [Errno -2] Name or service not known)
