Yang Wang commented on FLINK-18725:
-----------------------------------

The root cause is port {{30025}} in the azure machine may be occupied by some 
other process(e.g. azure daemon, random port, etc.). So i suggest to use 
{{ClusterIP}} in the internal service. Just like what we have described in the 
document[1], only the rest service need to be exposed. I will create a PR for 
this ticket.
