Could not resolve ResourceManager address on Flink 1.7.1

Hello:

I am trying to set up a standalone flink cluster (1.7.1) and I'm getting a
very similar error as the user reported in
this
<http://mail-archives.apache.org/mod_mbox/flink-user/201809.mbox/%3CCAGr9p8BGrC81q1SDZN=PDnmL2g4jU0Gb3TEPkaKhY=EUoB9QBw@mail.gmail.com%3E>
thread. However, I believe the root cause should be different -- as I tried
start job manager using both start-cluster.sh and jobmanager.sh but both of
them failed with the same error.
The error I got is on task manager (flink-worker1) is similar to the
following:

But the job manager seems to start up ok:

Interestingly, the worker node (flink-worker1) never seems to connect to
the jobmanager since it keeps retrying. But when I force the task manager
to close, job manager reports an error at the end saying the association
has failed. For some reason, none of the job manager managed to connect
even though port 6123 on the job manager is open and listening.

Any suggestion will be appreciated.

Thanks!
