William Guo commented on GRIFFIN-198:
-------------------------------------
hi [~chemikadze]
Sorry, I will reopen this ticket.
For this issue,
https://github.com/apache/incubator-griffin/blob/master/service/src/main/java/org/apache/griffin/core/metastore/hive/HiveMetaStoreServiceImpl.java#L119-L123
the bottom line is we cannot return or cache incomplete db->tables map to
users.
I think we need to make it transparent to our users, so let us retry it first,
but we need to ensure it works well with cache.
Thanks,
William

> Project: Griffin (Incubating)
> Issue Type: Bug
> Reporter: Nikolay Sokolov
> Assignee: William Guo
> 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.
