Description

Seems it's common that HMS metastore may have incorrect metadata for one or more databases/tables/partitions due to various reasons (see SENTRY-1564). Right now, HMS will not start properly if MetastoreCacheInitializer fails to initialize authzPath and the whole Hive service becomes unusable.

Propose to continue the cache initialization even there is a task failure. The databases/tables with the issues will be unusable until the authzPath cache for them is built.
