气流：ValueError：无法配置处理程序“处理器”-wasb 记录器

Question

我正在尝试使用 Azure blob 配置远程日志记录。

Airflow version: 1.10.2
Python: 3.6.5
Ubuntu: 18.04

以下是我执行的步骤：

1. 在 $AIRFLOW_HOME/config/log_config.py 中，我放了 REMOTE_BASE_LOG_FOLDER = 'wasb-airflow-logs'（这是容器内的一个文件夹（容器名称：airflow-logs））
2. 空的 init.py 位于 $AIRFLOW_HOME/config/
3. $AIRFLOW_HOME/config/ 被添加到 $PYTHONPATH
4. 在 $AIRFLOW_HOME/config/log_config.py 中将 DEFAULT_LOGGING_CONFIG 重命名为 LOGGING CONFIG
5. Airflow blob 连接中定义的用户对 REMOTE_BASE_LOG_FOLDER 具有读/写访问权限
6. $AIRFLOW_HOME/airflow.cfg 它有 remote_logging = True logging_config_class= log_config.LOGGING_CONFIG remote_log_conn_id =

以下是错误：

Unable to load the config, contains a configuration error.
Traceback (most recent call last):
  File "/home/gsingh/anaconda3/lib/python3.6/logging/config.py", line 382, in resolve
    found = getattr(found, frag)
AttributeError: module 'airflow.utils.log' has no attribute 'wasb_task_handler'

During handling of the above exception, another exception occurred:

    self.importer(used)

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

ValueError: Unable to configure handler 'processor': Cannot resolve 'airflow.utils.log.wasb_task_handler.WasbTaskHandler': cannot import name 'logging_class_path'

我不确定我缺少哪个配置。有人遇到过同样的问题吗？

Answer 1

您需要安装 azure 包。

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

根据updating.md

现在应该安装

pip install apache-airflow[azure]

但这对我不起作用。
