NullPointerException when calling get_range_slice()
---------------------------------------------------
Key: CASSANDRA-643
URL: https://issues.apache.org/jira/browse/CASSANDRA-643
Project: Cassandra
Issue Type: Bug
Components: Core
Affects Versions: 0.5
Environment: Linux
Reporter: Jonathan Hseu
This bug affects 0.5.0beta2.
In the SlicePredicate struct, column_names is defined as "optional", and so can
be null.
get_range_slice() passes the "predicate.getColumn_names()" to
"ThriftValidation.validateColumns()" without first checking if it's null,
resulting in the following exception:
java.lang.NullPointerException

org.apache.cassandra.service.ThriftValidation.validateColumns(ThriftValidation.java:162)

Strangely enough, calling it from python doesn't generate this exception, but
calling it from C++ does, with the following code:
shared_ptr<TTransport> transport(new TSocket(host, port));
shared_ptr<TProtocol> proto(new TBinaryProtocol(transport));
CassandraClient client(proto);
transport->open();
ColumnParent column_parent;
column_parent.column_family = "Test";
SlicePredicate slice_predicate;
std::vector<KeySlice> keys;
client.get_range_slice(keys, keyspace, column_parent, slice_predicate, "", "",
100, ONE);
The fix is trivial, just check that predicate.getColumn_names() is not null in
line 562 of CassandraServer.java
