Sergey Shelukhin commented on HIVE-5225:
----------------------------------------
The problem with that is that if it exists, it will be dropped... I linked jira
which I coincidentally filed today morning. This class has access to all the
HiveMetastoreClient calls, so it can remember the name of existing database and
call getDatabase on it instead
> There is no database named nonexistentdatabaseusedforhealthcheck
> ----------------------------------------------------------------

> Key: HIVE-5225
> URL: https://issues.apache.org/jira/browse/HIVE-5225
> Project: Hive
> Issue Type: Bug
> Affects Versions: 0.11.0
> Reporter: Eugene Koifman
> Fix For: 0.12.0
>
>
> HiveClientCache.CacheableHiveMetaStoreClient.isOpen() tries to do a health
> status check of the connection. This causes the following exception to be
> written to the log file. It needlessly pollutes the log file and cause alarm
> for customers.
> The exception itself is produced by the metastore so the client can't
> suppress it.
> Metastore should not log this since this is clearly a user error. It should
> instead throw an exception to the client (or return an error some other way).
