> 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
> Fix For: 2.1.x
>
> Attachments: schema.txt
>
>
> The schema that was being used when this error was produced is attached.
> 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:
> {code}
> <ErrorMessage code=0000 [Server error]
> message="java.nio.BufferUnderflowException">
> {code}
> 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:
> {code}
> ERROR [main] 2014-09-30 13:43:04,183 CassandraDaemon.java:474 - Exception

> 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.
