Nikolay Sokolov commented on GRIFFIN-198:
-----------------------------------------
[~guoyp] Aside nulls, I've mentioned second problem in a ticket -- getTables
call returns only partial result, if it fails. In these cases, result will be
non-empty and will be cached, while still being incomplete. Variety of
implementations is possible, from retries in that function to returning 5xx
errors back to user -- what's your view on it?
> HiveMetaStoreServiceImpl caches incorrect state of metastore

> Key: GRIFFIN-198
> URL: https://issues.apache.org/jira/browse/GRIFFIN-198
> Project: Griffin (Incubating)
> Issue Type: Bug
> Reporter: Nikolay Sokolov
> Priority: Major
>
> Currently, HiveMetaStoreServiceImpl is caching:
> * nulls and empty lists in some methods, when metastore request failed for
> some reason
> * empty list of tables as response to getAllTable(String) and getAllTable()
> calls
> Both problems result in confusing output on large amount of tables.
