Subject [jira] [Updated] (CASSANDRA-8029) BufferUnderflowException when writing a null value to a UDT field
Date Tue, 30 Sep 2014 18:34:37 GMT

     [ https://issues.apache.org/jira/browse/CASSANDRA-8029?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Cory Snyder updated CASSANDRA-8029:
-----------------------------------
    Description: 
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:

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.
