>
> In IMPALA-12286, catalogd re-generate its Catalog Service ID in JniCatalog
> when it becomes active. But CatalogServiceCatalog is not updated when new
> Catalog Service ID is generated. This causes coordinator hanging when
> processing DDLs.
> In CatalogServer class, member variable is_active_ is not protected by mutex
> catalog_lock_, and pending_topic_updates_ is not cleared when the catalogd
> becomes active. It's possible catalog server sends pending catalog topic
> updates with old Catalog Service ID then sends catalog topic updates with new
> Catalog Service ID.
