Istvan Toth reassigned PHOENIX-6003:
------------------------------------

    Assignee:     (was: Istvan Toth)

> Metadata operations via Avatica turn empty string args to null
> --------------------------------------------------------------
>
>                 Key: PHOENIX-6003
>                 URL: https://issues.apache.org/jira/browse/PHOENIX-6003
>             Project: Phoenix
>          Issue Type: Bug
>          Components: queryserver
>    Affects Versions: queryserver-6.0.0
>            Reporter: Istvan Toth
>            Priority: Major
>
> PhoenixDatabaseMetaData.getTables(), and some other functions have parameters 
> (catalog, schemaPattern), where null and empty String have different 
> semantics.
> The corresponding protobuf fields in Avatica are not nullable, and PQS seems 
> to interpret empty string as Null, making it impossible to get the default 
> catalog/schema only.
