[jira] [Created] (CASSANDRA-8029) BufferUnderflowException when
writing a null value to a UDT field
Cory Snyder created CASSANDRA-8029:
--------------------------------------
Summary: BufferUnderflowException when writing a null value to a UDT field
Key: CASSANDRA-8029
URL: https://issues.apache.org/jira/browse/CASSANDRA-8029
Project: Cassandra
Issue Type: Bug
Environment: Ubuntu 14.04. Cassandra 2.1.0. Single node.
Reporter: Cory Snyder
This error was produced with the following schema:
CREATE TYPE LB_POOL_HEALTH_CHECK (
mode text,
uri text,
health_threshold text,
unhealth_threshold text,
interval text,
timeout text
);
CREATE TYPE LB_POOL_SERVICE_PORT (
enabled boolean,
protocol text,
algorithm text,
port text,
health_check_port text,
health_checks set<frozen<lb_pool_health_check>>
);
CREATE TYPE LB_POOL_MEMBER (
ip_address text,
weight text,
service_ports set<frozen<lb_pool_service_port>>
);
CREATE TYPE LB_PERSISTENCE_TYPE (
method text,
cookie_name text,
cookie_mode text
);
CREATE TYPE LB_VIRTUAL_SERVER_SERVICE_PROFILE (
enabled boolean,
protocol text,
port text,
persistence frozen<lb_persistence_type>
);
CREATE TYPE LOAD_BALANCER_POOL (
id text,
name text,
description text,
service_ports set<frozen<lb_pool_service_port>>,
members set<frozen<lb_pool_member>>,
operational boolean,
error_details text
);
CREATE TYPE LOAD_BALANCER_VIRTUAL_SERVER (
name text,
enabled boolean,
description text,
ip_address text,
service_profiles set<frozen<lb_virtual_server_service_profile>>,
logging boolean,
pool text,
network text
);
CREATE TABLE LOAD_BALANCER_SERVICE (
edge_uuid text,
enabled boolean,
pools set<frozen<load_balancer_pool>>,
virtual_servers set<frozen<load_balancer_virtual_server>>,
PRIMARY KEY (edge_uuid)
);
Whenever I write a null value to any of the id, name, or description fields for a LOAD_BALANCER_POOL udt in the pools set of the LOAD_BALANCER_SERVICE table or to the name, enabled, description, or ip_addresses fields of the LOAD_BALANCER_VIRTUAL_SERVER table in the virtual_servers set of the LOAD_BALANCER_SERVICE table, I get the following error from cqlsh:
<ErrorMessage code=0000 [Server error] message="java.nio.BufferUnderflowException">
When doing the same from the Java Datastax driver, this seems to succeed on the first write but fail with a timeout exception on all subsequent writes until either the table is truncated or both the pools and virtual_servers collections are both written as empty sets.
Having null values in other UDT fields in the hierarchy doesn't seem to cause any issues.
When I restart Cassandra after having these errors, Cassandra fails to start and throws the following error when trying to replay the commit logs:

I'm not sure if null values are supposed to be acceptable for UDT fields, but in any case, it would be nice to handle these errors more gracefully.
