Hi Harshith,
I'm not an expert of how to setup nginx with authentication for Flink but I
could shed some light on the redirection problem. I assume that Flink's
redirection response might not be properly understood by nginx. The good
news is that with Flink 1.8, we no longer rely on client side redirection
responses but instead proxy internally. This means that the
RestServerEndpoint will contact the leading JobManager and retrieve the
required information without a redirect. Upgrading to Flink 1.8.2 might
solve this particular problem.
Cheers,
Till
