CM 5.8.1 CDH 5.8.0 Spark History WebUI redirects to SSL but no configuration

[#1]

Using CM 5.8.1 and CDH 5.8.0

The Spark History WebUI link automatically goes to https://HOSTNAME:18088 and chrome immediately reports ERR_SSL_PROTOCOL_ERROR

Attempting to manually hit http://HOSTNAME:18088 automatically pushes the connection to https and reports the same error.

There is still no configuration for spark history server SSL.

Tried the configuration here: http://spark.apache.org/docs/latest/configuration.html#encryption and placing it in the advanced configuration snippet, but that just leads to a set of new errors.

Anyone else encounter this? It was working fine on CM/CDH 5.7.1

If you are getting directed to an https address even though you do not have TLS configured, it is likely Chrome's HSTS support that is forcing you to an HTTPS address based on the hostname.

In chrome, go to:

chrome://net-internals/#hsts

In Query domain, enter in your hostname or your domain.

If something is returned, enter it in the Delete domain text box and Delete.

Thank you. I guess I haven't visited that URL in a while so I mis-attributed it to the upgrade.
