Я пытаюсь использовать Azure Blob Storage с Apache Flink 1.10 для целей контрольных точек.
Я выполнил все инструкции, упомянутые в [Документация Flink] [1] https://ci.apache.org/projects/flink/flink-docs-release-1.10/ops/filesystems/azure.html
Шаг 1:
mkdir ./plugins/azure-fs-hadoop
cp ./opt/flink-azure-fs-hadoop-1.10.0.jar ./plugins/azure-fs-hadoop/
Шаг 2:
Это то, что у меня есть в flink-conf. xml
#Azure Storage Key
**fs.azure.account.key.<storage-account>.blob.core.windows.net:xxxxxxxxxxxxxxxxxx**
Шаг 3:
Использование Azure Хранение BLOB-объектов для контрольных точек
Это то, что у меня есть в моей работе Flink
final StateBackend stateBackend = new FsStateBackend("wasb://flink-blob@$<storage-account>.blob.core.windows.net/checkpoint");
Я не уверен, что здесь что-то пропустил, но когда я отправляю работу, я получаю ниже Exception (AskTimeoutException от Actor).
