-------------------------------------------
Summary: fqltool dump results NPE when null value inserted using
prepared query
Key: CASSANDRA-18113
URL: https://issues.apache.org/jira/browse/CASSANDRA-18113
Project: Cassandra
Issue Type: Bug
Components: Tool/fql
Reporter: n.v.harikrishna
Enable fullquerylog, prepare insert statement and bind it with a null value and
execute it. Executing fqltool dump after insert will result into
NullPointerException.
Stept to reproduce:
* Create cluster using ccm
* Create a table something like:
{code:java}
CREATE TABLE ks1.t2 (
id int PRIMARY KEY,
value text
) ;
{code}
* Execute below code
{code:java}
try (CqlSession cqlSession = CqlSession.builder().build()) {
PreparedStatement preparedStatement = cqlSession.prepare("INSERT INTO
ks1.t2 (id, value) VALUES (?, ?)");
cqlSession.execute(preparedStatement.bind(6, null));
}
{code}
* Now running fqltool dump. It will run into NPE
Stack trace:
{code:java}
error: null
