Quanlong Huang commented on IMPALA-4105:
----------------------------------------
Prioritize this. Too many partition level refreshes on the same table is a more
severe problem in local catalog mode since the catalog version changes
frequently on the table. getPartialCatalogObject requests from coordinators
might see inconsistent metadata due to this and coordinators have to retry,
which adds into the query planning time.
