Unable to see Coordinator UI

Hi,

We are not able to see coordinator UI screen while using imply imply-2.8.0.

Kindly suggest solution.

Thanks in advance.

Amit

Please check IMPLY_FOLDER/var/sv/coordinator/current log file and see if coordinator is working good.

Thanks & Rgds

Hi Amit,

This error can occur on startup but is harmless unless it keeps repeating itself.

Does the coordinator whose IP you are using for the coordinator console show that it’s the leader?

http://druid.io/docs/latest/operations/api-reference.html#coordinator

Hi,

yes the coordinator ip which i am using shows that its a leader.

Did you happen to have enabled the basic-auth on Druid? http://druid.io/docs/latest/development/extensions-core/druid-basic-security.html

Thanks for reply,
But is it compulsory to add ‘basic auth’ ?

As when I was using previous version of druid, without adding this authentication I was able to see the coordinator UI.

Amit

Hi,

PLEASE HELP---------------

Below is my common.runtime.properties:

Hi Amit,

Did you try https instead of http? What about a different browser?

Best,

Caroline
