Я следил за установкой вики https://github.com/edx/edx-analytics-pipeline/wiki/Running-the-analytics-backend-locally

Я запускаю Ubuntu 16.04

Я получил ошибку при выполнении команды 

 launch-task AnswerDistributionToMySQLTaskWorkflow --local-scheduler
 --remote-log-level DEBUG --include *tracking.log* --src /tmp/log_files --dest /tmp/answer_dist --mapreduce-engine local --name test_task

Мой файл журнала имеетбыл сохранен в / tmp / log_files, как указано в установочной вики

Отображаемая ошибка приведена ниже
