Berry Österlund commented on AMBARI-18479:
------------------------------------------

I acutally have the same problem from normal servicechecks, and I get a warning on the standby
node due to the following error

> If both HA and SPNEGO is configured for the cluster, the service check fails on Yarn.
> The problem is because we are using curl to fetch the http pages, we also enters –L
to follow the location information in the header. But –L don’t forward authentication
information to redirected hosts. Changing –L to --location-trusted solves the problem.
