-----------------------------------
Summary: Querying by secondary index on collection column returns
NullPointerException sometimes
Key: CASSANDRA-13246
URL: https://issues.apache.org/jira/browse/CASSANDRA-13246
Project: Cassandra
Issue Type: Bug
Environment: [cqlsh 5.0.1 | Cassandra 3.7 | CQL spec 3.4.2 | Native
protocol v4]
One cassandra node up, with consistency ONE
Reporter: hochung
Not sure if this is the absolute minimal case that produces the bug, but here
are the steps for reproducing.
1.
```CREATE TABLE test (
id text,
ck1 text,
ck2 text,
static_value text static,
set_value set<text>,
primary key (id, ck1, ck2)
);
```
2. Create secondary indices on the clustering columns, static column, and
collection column
```
create index on test (set_value);
create index on test (static_value);
create index on test (ck1);
create index on test (ck2);
```
3. Insert a null value into the `set_value` column
```
insert into test (id, ck1, ck2, static_value, set_value) values ('id', 'key1',
'key2', 'static', {'one', 'two'} );
```
Sanity check:
```
select * from test;
id | ck1 | ck2 | static_value | set_value
----+------+------+--------------+----------------
id | key1 | key2 | static | {'one', 'two'}
```
4. Set the set_value to be empty
```
update test set set_value = {} where id = 'id' and ck1 = 'key1' and ck2 =
'key2';
```
5. Make a select query that uses `CONTAINS` in the `set_value` column
```
select * from test where ck2 = 'key2' and static_value = 'static' and set_value
contains 'one' allow filtering;
```
Here we get a ReadFailure:
```
ReadFailure: Error from server: code=1300 [Replica(s) failed to execute read]
message="Operation failed - received 0 responses and 1 failures"
info={'failures': 1, 'received_responses': 0, 'required_responses': 1,
'consistency': 'ONE'}
```
Logs show a NullPointerException
