> Today if we disable calculation of stats via {{phoenix.stats.collection.enabled}} property, it creates {{NoopStatisticsCollector}}. If someone calls "UPDATE STATISTICS <TABLE-NAME>", it will create NoopStatisticsCollector, scan the whole table and does nothing. This is fixed in 4.15 via PHOENIX-4009. If we don't want to backport PHOENIX-4009, we can fix this bug just in 4.14
