When deploying version v305, the master cannot establish a connection with the worker.

[liiuzq-xiaobai]

Alluxio Version:
v305

Describe the bug
The contents of alluxio-site.properties are as follows：

After I successfully formatted using command"alluxio init format" and started the cluster using "alluxio process start all", the master.log reported an error. This error looks like the master is unable to establish a connection with the worker via rpc **To Reproduce** See steps above

Expected behavior
The cluster can be set up successfully, and the master can detect the activity of all workers.

Urgency
yes

Are you planning to fix it
Maybe

Additional context
no

Hi, if you set alluxio.worker.membership.manager.type=STATIC may cause this problem, you should also set worker address in conf/workers.
But I recommend alluxio.worker.membership.manager.type=ETCD , which is the newly update in Alluxio 3.x
OR alluxio.worker.membership.manager.type=MASTER is same to the Alluxio 2.x

Thanks!Is the master currently only used to manage various jobs?
