No available Impalad to send queries to

Yes, I have those two set, along with a bunch of others under the Security tab in the Hue configuration.

Ahhh, that is why:-). Those properties:

[desktop]
ldap_username
ldap_password

Tell Hue to use ldap when authenticating against Impala and HS2. So if you're not using ldap for Impala and HS2, then you can remove those and you don't need ldap for Impala.

Good to know, thanks! Hue is indeed using LDAP to authenticate against HS2. I think it would be helpful to have a message in the log to point admins in the right direction :)

Jira filed:-)

https://issues.cloudera.org/browse/HUE-2749

Right now Hue requires both Impala and HS2 to be configured for Ldap, so ldap_username and ldap_password are global. There is also a feature request out there to make those specific for Impala and HS2 so that would be less of an issue in the future.

+1 !



Re: No available Impalad to send queries to

can you kindly tell me how to configure HS2 for LDAP. 

I have an environment in which Impala and Hue are LDAP configured but i dont know how to configure HS2 for LDAP. 

 

Thanks in advance.

Re: No available Impalad to send queries to

Hi again,
Thanks, Hue works with LDAP enabled Impala, but if i enable SSL on impala, Hue gives the same error again i.e. "No available Impalad to send queries to"
Is there a workaround for it ?
Thanks

Re: No available Impalad to send queries to

You need to configure the [impala] section of Hue to use SSL, e.g.
