-----------------------------------------
Summary: 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
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
