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);

或者

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,我得到一个StreamingException “进程失败('流式作业失败!')”

并在控制台输出中看到以下错误:

packageJobJar: [] [/C:/Hadoop/hadoop-1.1.0-SNAPSHOT/lib/hadoop-streaming.jar] C: \Users\user1\AppData\Local\Temp\1\streamjob6525516867576872971.jar tmpDir=null

13/08/26 12:30:51 ERROR streaming.StreamJob: Error Launching job : Input path do es not exist: hdfs:/devstoreaccount1/testcontainer/input 

Streaming Command Failed!

有什么提示吗?

您可以使用以下路径之一访问本地存储模拟器。

wasb://testcontainer@storageemulator/input

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)
