> RangerUserStoreCache.getLatestRangerUserStoreOrCached() currently refreshes the cache when the provided lastKnownUserStoreVersion is different from the version in the database. Instead, the cache should be refreshed only when the version cached is different from the version in the database. This will help avoid unnecessary load on the database - for example, whenever a plugin downloads userstore.
