Ошибка чтения Кассандры

Question

tl; dr Я решил проблему обновления до Cassandra 3.2. This bug, по-видимому, вызывал проблему.

---

Я бегу два-узла кластер Кассандры с версиями [cqlsh 5.0.1 | Cassandra 3.0.1 | CQL spec 3.3.1 | Native protocol v4].

Существует одна таблица, в которой я не могу читать, у меня есть следующее сообщение об ошибке:

cqlsh:kepler> select type from md_data limit 1; 
Traceback (most recent call last): 
    File "/local/chernals/dsc-cassandra-3.0.1/bin/cqlsh.py", line 1258, in perform_simple_statement 
    result = future.result() 
    File "/local/chernals/dsc-cassandra-3.0.1/bin/../lib/cassandra-driver-internal-only-3.0.0-6af642d.zip/cassandra-driver-3.0.0-6af642d/cassandra/cluster.py", line 3122, in result 
    raise self._final_exception 
ReadFailure: 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'} 

я могу прочитать другие таблицы без каких-либо проблем.

Схема этой таблицы:

CREATE TABLE kepler.md_data (
    name text, 
    tag text, 
    id timeuuid, 
    parameter frozen<parameter>, 
    blob_value blob, 
    real_value float, 
    telegram map<text, text> static, 
    text_value text, 
    type text, 
    PRIMARY KEY ((name, tag, id), parameter) 
) WITH CLUSTERING ORDER BY (parameter 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 INDEX parameter_idx ON kepler.md_data (parameter); 

Будут ли какие-то проблемы с такой схемой и различные версии Cassandra/cqlsh я бегу?

Обратите внимание, что, когда таблица пуста, я могу «прочитать» ее (она пуста, но оператор select успешно завершен).

Edit:

Супер странная проблема, как я с трудом воспроизводя все это время. Я перешел на тестовую установку только с одним узлом. Кажется, что оно связано с количеством строк, присутствующих в таблице.

cqlsh:kepler> TRUNCATE TABLE md_data;

(0 rows)
