我正在尝试为hdinsight创建一个简单的map / reducer作业,但我无法通过 ASV://
将本地hdinsight hadoop集群中的作业连接到本地azure存储模拟器示例代码如下:
var hadoop = Hadoop.Connect();
HadoopJobConfiguration config = new HadoopJobConfiguration();
config.InputPath = @"asv://127.0.0.1:10000/devstoreaccount1/testcontainer/input";
config.OutputFolder = "asv://127.0.0.1:10000/devstoreaccount1/testcontainer/output";
hadoop.MapReduceJob.Execute<Mapper1>(config);
或
var hadoop = Hadoop.Connect();
HadoopJobConfiguration config = new HadoopJobConfiguration();
config.InputPath = @"asv://testcontainer/input";
config.OutputFolder = "asv://testcontainer/output";
hadoop.MapReduceJob.Execute<Mapper1>(config);
其中 testcontainer 是本地模拟器的blob存储中的现有容器。 运行此代码时,我得到 StreamingException “处理失败('流媒体作业失败!')”
在控制台输出中看到以下错误:

任何提示?

您可以使用以下路径之一访问本地存储模拟器。
wasb:// testcontainer @ storageemulator /输入
wasb:/// input(当存储模拟器设置为默认文件系统时)
asv:/// input(当存储模拟器设置为默认文件系统时,asv已过时,不推荐使用)
