> Reporter: Vihang Karajgaonkar
> Assignee: Vihang Karajgaonkar
> Priority: Major
> Fix For: Impala 4.0
>
>
> CatalogServiceCatalog.isBlacklistedDb() is used in many places to check if a
> given database name is on the list of databases which should be ignored in
> Catalog. However it does a case sensitive comparison which could cause false
> negatives.
> One place where we see this issue is when we receive a metastore event on the
> on {{SYS}} database and the {{--blacklisted_dbs}} is set to \{{sys}}. In such
> cases EventsProcessor should ignore the event instead of processing it.
