Description

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.
