----------------------------------------
Summary: NPE in CqlRecordWriter: Related to
AbstractCassandraStorage handling null values
Key: CASSANDRA-6180
URL: https://issues.apache.org/jira/browse/CASSANDRA-6180
Project: Cassandra
Issue Type: Bug
Components: Hadoop
Environment: Pig, CqlStorage
Reporter: Henning Kropp
I encountered an issue with the {{CqlStorage}} and it's handling of null
values. The {{CqlRecordWriter}} throws an NPE when a value is null. I found a
related ticket CASSANDRA-5885 and applied the there state fix to the
{{AbstractCassandraStorage}}.
Instead of converting {{null}} values to {{ByteBuffer.wrap(new byte[0])}}
{{AbstractCassandraStorage}} returns {{(ByteBuffer)null}}
This issue can be reproduced with the attached files: {{test_null.cql}},
{{test_null_data}}, {{null_test.pig}}
A fix can be found in the attached patch.
