Some code does not expect from the logger code to throw, and this can lead to the problems like: - marking distributed batch as broken (in StorageDistributedDirectoryMonitor) - some MergeTree code may also be affected. So instead of throwing the exception, it will be logged to the stderr (if it is possible).
