Airflow: ValueError: Невозможно настроить обработчик 'процессор' - регистратор wasb

Question

Я пытаюсь настроить удаленное ведение журнала с помощью BLOB-объекта Azure.

Airflow version: 1.10.2
Python: 3.6.5
Ubuntu: 18.04

Вот шаг, который я сделал:

1. В $ AIRFLOW_HOME / config / log_config.py я поместил REMOTE_BASE_LOG_FOLDER = 'wasb-airflow-logs' (это папка внутри контейнера (имя контейнера: airflow-logs))
2. Пусто init .py находится в $ AIRFLOW_HOME / config /
3. $ AIRFLOW_HOME / config / добавлено в $ PYTHONPATH
4. Переименовано в DEFAULT_LOGGING_CONFIG в LOGGING CONFIG везде в $ AIRFLOW_HOME / config / log_config.py
5. Пользователь, определенный в подключении BLOB-объекта Airflow, имеет доступ на чтение / запись к REMOTE_BASE_LOG_FOLDER
6. $ AIRFLOW_HOME / airflow.cfg имеет значение remote_logging = True logging_config_class = log_config.LOGGING_CONFIG remote_log_conn_id =

Ниже приведена ошибка:

Unable to load the config, contains a configuration error.

    found = getattr(found, frag)

During handling of the above exception, another exception occurred:

The above exception was the direct cause of the following exception:

Я не уверен, какую конфигурацию мне не хватает. Кто-нибудь сталкивался с такой же проблемой?

Answer 1

Вам необходимо установить пакет Azure.

pip install 'apache-airflow[azure_blob_storage,azure_data_lake,azure_cosmos,azure_container_instances]

Согласно update.md

Теперь он должен быть установлен с

pip install apache-airflow[azure]

Но это не сработало для меня.
