Aleksey Zinoviev commented on IGNITE-12054:
-------------------------------------------
An ExternalCatalog was refactored and all listener properties were inherited in
ExternalCatalogWithListener.
Nobody yet inherited from this class on Github, the known implementations are
HiveExternalCatalog and MemoryExternalCatalog (both of them doesn't support
listeners and events)
Also, people in Spark ML couldn't solve the same problem
