Subject Re: JobManager web interface redirect strategy when running in HA
Date Wed, 01 Nov 2017 11:34:30 GMT
We intend to change the redirection behavior such that any jobmanager 
(leading or not) can
accept requests, and communicates internally with the leader. In this 
model you could setup
the flink.domain.tld to point to any jobmanager (or distribute requests 
among them).

Would this work for you?

I believe this is targeted for 1.5.
