GPUdb object instantiation throws Missing value for 'conf.np1.enable_head_failover' Error

[ghifariram]

Hi guys,

I'm trying to instantiate the gpudb.GPUdb object using this code snippet:

import gpudb

credentials = {
'host': 'xx.xx.xx.xx',
'port': 9191,
'user': 'username',
'pass': 'password'
}
 
db_obj = gpudb.GPUdb(
    host=f"http://{credentials['host']}",
    port=credentials['port'],
    username=credentials["user"],
    password=credentials["pass"],
) 

But I got this error:
GPUdbException: "Missing value for 'conf.np1.enable_head_failover' in system properties"

I'm on the client side so I don't know & don't have control over how the server is configured and its system properties.

Is this expected behavior? Based on the docs, I believe conf.np1.enable_head_failover has a default value so we don't necessarily need to specify it on the /opt/gpudb/core/etc/gpudb.conf file

I'm using gpudb==7.1.5.0

@ghifariram - this looks like a problem that might occur when using a 7.1 API to connect to a 7.0 (or older) database. If so, switch to a 7.0 API (7.0.20.1 is the latest) and try again. If not, can you let me know the version of the server you're trying to connect to and what type of installation it is (cloud, original 7.1 on-prem, 7.0 -> 7.1 upgraded on-prem, etc.)?

Thanks,
Kyle
