无法从 GAE 标准环境执行 Dataflow 作业？

分类：编程问答

如何解决无法从 GAE 标准环境执行 Dataflow 作业？

我正在尝试从 GAE 标准环境中的 servlet 启动数据流管道作业。该作业从 Cloud SQL 数据库读取并在 BigQuery 中写入，两者都在同一个项目中。我猜云数据流服务帐户拥有所有需要的权限（存储对象管理员、云 SQL 客户端、BigQuery 管理员、BigQuery 数据编辑器）。我收到以下异常：

我设法在 GAE 标准上运行它。问题是我从未将它安排在 cron 作业上，只是通过 URL 触发器运行它。所以在一个小时内，我安排了十几个请求，其中大部分都通过了。但有些人因为这个例外失败了：

我的 appengine-web.xml 看起来像这样：

<?xml version="1.0" encoding="utf-8"?>
<appengine-web-app xmlns="http://appengine.google.com/ns/1.0">

    <application>my-app-name</application>


    <version>1</version>
    <threadsafe>true</threadsafe>
    <sessions-enabled>true</sessions-enabled>
    <runtime>java8</runtime>

    <system-properties>
        <property name="java.util.logging.config.file" value="WEB-INF/logging.properties"/>
        <property name="file.encoding" value="UTF-8" />
        <property name="DEFAULT_ENCODING" value="UTF-8" />
    </system-properties>

    <instance-class>F1</instance-class>

    <automatic-scaling>
        <min-idle-instances>0</min-idle-instances>
        <max-idle-instances>1</max-idle-instances>
    </automatic-scaling>

</appengine-web-app>

cron servlet 非常简单：

public class CronServlet extends HttpServlet {

    @Override
    protected void doGet(HttpServletRequest req,HttpServletResponse resp) {
        String command = req.getParameter("command");
        if (command == null) {
            return;
        }

        if (command.equals("dataflow-job-test")) {
            CloudSqlToBigQueryExporter.doTestOnExp();
            //return;
        }
    }


    @Override
    protected void doPost(HttpServletRequest req,HttpServletResponse resp) {
        doGet(req,resp);
    }
}

cron.yaml 是这样的：

cron:
- url: '/cron?command=dataflow-job-test'
  schedule: 'every 5 minutes'
  description: 'Dataflow job execution test'

解决方法

您在此处遇到的问题，如错误消息中所述：

Operation not allowed in a thread that is neither the original request thread nor a thread created by ThreadManager

是因为您的 servlet 正在创建 App Engine 中不允许的新线程，除非您使用 GAE's Thread Manager 而不是使用传统线程。

因此，为了解决这个问题，您需要更改代码以使用 currentRequestThreadFactory() 生成线程。
