Zhu Zhu updated FLINK-14452:
----------------------------
Description:
With FLINK-14450 and FLINK-14451, the SchedulingTopology and FailoverTopology
are able to share one default implementation.
Currently there are 3 failover topology instances created, 2 permanently kept
in JM. 2 scheduling topology instances created permanently kept in JM. This can
be a waste of
We can change the scheduler to create and keep only one such an execution
topology instance to reduce the cost to build and host execution topologies.
More details see FLINK-14330 and the [design
doc|https://docs.google.com/document/d/1f88luAOfUQ6Pm4JkxYexLXpfH-crcXJdbubi1pS2Y5A/edit#].
