Chesnay Schepler commented on FLINK-8700:
-----------------------------------------

[~mingleizhang] is correct, we can't remove the method as it is used by the 
`MiniClusterResource` to create a legacy cluster.

We should however look at other usages, but I'm doing that already as part of 
FLINK-8703.

> Quite some ITCases rely on {{FlinkMiniCluster}} and its subclasses 
> ({{LocalFlinkMiniCluster}} and {{TestingCluster}}). This means they use the 
> legacy {{JobManager}} and {{TaskManager}} and not the new FLIP-6 components 
> which are enabled by default in Flink 1.5.0.
> {{AbstractTestBase}} uses the new {{MiniClusterResource}} which encapsulates 
> creation of a FLIP-6 cluster or legacy cluster. We should use this in all 
> ITCases, which probably means that we have to extend it a bit, for example to 
> allow access to a {{ClusterClient}}.
> Transitively, {{TestBaseUtils.startCluster()}} also uses the legacy 
> {{LocalFlinkMiniCluster}}.
