Hi,
It’s great to help out. :)
Setting 127.0.0.1 instead of “localhost” in jobmanager.rpc.address,
helped to build the connection to the jobmanager. Apparently localhost
resolving is different in webclient and the jobmanager. I think it’s good to
set "jobmanager.rpc.address: 127.0.0.1" in future builds.
But then I get this error when I tried to run examples. I don’t know if
I should move this issue to another thread. If so please tell me.
