Protobuf RPC在Hadoop 2.2.0单节点服务器上不可用？ [英] Protobuf RPC not available on Hadoop 2.2.0 single node server?

问题描述

我试图在本教程安装的本地单节点集群上运行hadoop 2.2.0 mapreduce作业：
http://codesfusion.blogspot.co.at/2013/10/setup-hadoop-2x-220- on-ubuntu.html？m = 1

I am trying to run a hadoop 2.2.0 mapreduce job on my local single node cluster installed by following this tutorial: http://codesfusion.blogspot.co.at/2013/10/setup-hadoop-2x-220-on-ubuntu.html?m=1

尽管在服务器端引发了以下异常：

Though on the server side the following exception is thrown:

org.apache.hadoop.ipc.RpcNoSuchProtocolException: Unknown protocol: org.apache.hadoop.yarn.api.ApplicationClientProtocolPB
at org.apache.hadoop.ipc.ProtobufRpcEngine$Server$ProtoBufRpcInvoker.getProtocolImpl(ProtobufRpcEngine.java:527)

有没有办法让我在服务器端配置Protobuf RPC？我需要hadoop本地库吗？或者我可以在客户端以某种方式切换到Writables / Avro RPC？

Is there a way for me to configure Protobuf RPC to be available on server side? Do I need the hadoop native libraries for this? Or can I switch somehow on the client side to Writables/Avro RPC?

推荐答案

好的，找到原因，我连接到yarn resourcemanager的错误端口。正确的配置是：
yarn.resourcemanager.address = localhost：8032

Ok, found the reason, I connected to the wrong port for the yarn resourcemanager. The correct configuration is: yarn.resourcemanager.address=localhost:8032
