Я новичок в Cassandra и YCSB и пытаюсь запустить бенчмаркинг на 3-узловом кластере cassandra, который построен с помощью docker-compose с YCSB.
Фаза загрузки YCSB завершилась за 4 часа без каких-либо ошибок или проблем, но на этапе выполнения я вижу ошибку READ-FAILED после загрузки в течение 2,5 часов (на 9212 секундах). Я пробовал запустить тот же тест пару раз, но увидел ту же проблему, не знаю почему.

Однако, когда я запускаю тестирование на MongoDB, он работает нормально, не обнаруживая никаких ошибок. Сообщите мне, нужно ли изменить какие-либо настройки или параметры при развертывании Cassandra yml или при запуске YCSB в кластере Cassandra.
Если вам понадобятся дополнительные журналы, дайте мне знать, они будут загружены по запросу. В настоящее время я загрузил 2 файла журнала (на github), один для журналов Docker и Cassandra и один для выполнения YCSB.
Любая помощь приветствуется.
