Istvan Toth commented on PHOENIX-6568:
--------------------------------------
Confirmed.
> NullPointerException in phoenix-queryserver-client not in
> phoenix-client-hbase
> --------------------------------------------------------------------------------
>
> Key: PHOENIX-6568
> URL: https://issues.apache.org/jira/browse/PHOENIX-6568
> Project: Phoenix
> Issue Type: Bug
> Components: queryserver
> Affects Versions: queryserver-6.0.1
> Reporter: Alejandro Anadon
> Priority: Major
>
> It may not be a bug and it's simply because I'm missing some concepts, but I
> guess the behavior of phoenix-client-hbase should be the same as
> phoenix-queryserver-client.
> If I run a simple query like:
> select null;
> In phoenix-queryserver-client I get a java.lang.NullPointerException, but in
> phoenix-client-hbase not.
>
> the query is reduced to the minimal concept, but I have the same result with
> other queries like:
> select null as SEQUENCE_CATALOG , SEQUENCE_SCHEMA , SEQUENCE_NAME ,
> START_WITH as START_VALUE , MIN_VALUE as MINIMUM_VALUE , MAX_VALUE as
> MAXIMUM_VALUE , INCREMENT_BY as "INCREMENT" FROM SYSTEM."SEQUENCE";
>
> this is the exception:
>
> org.apache.calcite.avatica.AvaticaSqlException: Error -1 (00000) : Error
> while executing SQL "select null": Remote driver error: NullPointerException:
