-----------------------------------------------

             Summary: NullPointerException on SELECT with SASI index
                 Key: CASSANDRA-12149
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-12149
             Project: Cassandra
          Issue Type: Bug
          Components: sasi
            Reporter: Andrey Konstantinov


If I execute the following sequence of queries, Cassandra aborts a connection reporting NPE
on server side.

CREATE KEYSPACE IF NOT EXISTS mykeyspace WITH REPLICATION = {'class' : 'SimpleStrategy', 'replication_factor'
: 1};

CREATE TABLE mykeyspace.myrecordtable (
    namespace text,
    entity text,
    timestamp bigint,
    feature1 bigint,
    feature2 bigint,
    PRIMARY KEY ((namespace, entity), timestamp)
) WITH CLUSTERING ORDER BY (timestamp ASC)
    AND bloom_filter_fp_chance = 0.01
    AND caching = {'keys': 'ALL', 'rows_per_partition': 'NONE'}
    AND comment = ''
    AND compaction = {'class': 'org.apache.cassandra.db.compaction.SizeTieredCompactionStrategy',
'max_threshold': '32', 'min_threshold': '4'}
    AND compression = {'chunk_length_in_kb': '64', 'class': 'org.apache.cassandra.io.compress.LZ4Compressor'}
    AND crc_check_chance = 1.0
    AND dclocal_read_repair_chance = 0.1
    AND default_time_to_live = 0
    AND gc_grace_seconds = 864000
    AND max_index_interval = 2048
    AND memtable_flush_period_in_ms = 0
    AND min_index_interval = 128
    AND read_repair_chance = 0.0
    AND speculative_retry = '99PERCENTILE';
CREATE CUSTOM INDEX record_timestamp_90e05e6caa714f29 ON mykeyspace.myrecordtable (timestamp)
USING 'org.apache.cassandra.index.sasi.SASIIndex';
CREATE CUSTOM INDEX record_feature1_90e05e6caa714f29 ON mykeyspace.myrecordtable (feature1)
USING 'org.apache.cassandra.index.sasi.SASIIndex';

INSERT INTO mykeyspace.myrecordtable (feature1, feature2, namespace, entity, timestamp) VALUES
(31, 32, 'ns2', 'entity3', 201606210131);
INSERT INTO mykeyspace.myrecordtable (feature1, feature2, namespace, entity, timestamp) VALUES
(11, 12, 'ns1', 'entity1', 201606210129);
INSERT INTO mykeyspace.myrecordtable (feature1, feature2, namespace, entity, timestamp) VALUES
(21, 22, 'ns2', 'entity2', 201606210130);

SELECT namespace, entity, timestamp, feature1, feature2 FROM mykeyspace.myrecordtable WHERE
namespace = 'ns2' AND entity = 'entity2' AND feature1 > 11 AND feature1 < 31  AND token(namespace,
entity) <= 9223372036854775807;
