------------------------------------
Summary: Change AbstractFlinkYarnClient from abstract to interface
Key: FLINK-1704
URL: https://issues.apache.org/jira/browse/FLINK-1704
Project: Flink
Issue Type: Improvement
Reporter: Henry Saputra
Assignee: Henry Saputra
Priority: Minor
The org.apache.flink.runtime.yarn.AbstractFlinkYarnClient is abstract but has
not default implementation of the methods.
It also used as variable type in Clifrontend#getClient which is kind of
anti-patter of an abstract class usages.
I would like to promote this to an interface to make it clear that it is type.
