Looking at Flink HA mode.
Why do you need to have the list of masters in the config if zookeeper is used
to keep track of them? In an environment like Google Cloud or Container Engine,
the JM may come back up but will likely have another IP address.
Is the masters config file only for bootstrapping or is it effectively to keep
track of JM nodes? Is it what TM nodes use to know their JobManager? Or do they
query Zookeeper?
In the scenario above (2 JMs, one fails, and comes back up as another instance,
with different IP) how does the JM join the cluster and how do TMs know about
the new JM?
ThanksE
