连接拒绝quickstart.cloudera：8020

问题描述

我正在使用Cloudera-quickstart 5.5.0 virtualbox

尝试在终端上运行此操作。正如你可以在下面，有一个例外。我已经寻找解决方案来解决这个问题，并找到了一些东西。

$ b 配置core-site.xml文件。

解决方案

网络配置不是您的问题。您不需要在虚拟机中触摸任何配置，您需要启动服务。例如，在这张图片中。左侧的HDFS服务被禁用，并且在最后一条命令上出现相同的错误。

您必须启动Cloudera Manager 和启动ZooKeeper，YARN和HDFS（按此顺序）。

要打开Cloudera Manager，请在虚拟机上的Firefox中转到 http：//quickstart.cloudera：7180 。

然后开始提及的服务。

启动服务后，您可以使用HDFS命令。

I'm using Cloudera-quickstart 5.5.0 virtualbox

Trying to run this on terminal. As you can below, there is an exception. I've searched for solution to solve this on internet and found something.

1-) configuring core-site.xml file. https://datashine.wordpress.com/2014/09/06/java-net-connectexception-connection-refused-for-more-details-see-httpwiki-apache-orghadoopconnectionrefused/

But I can only open this file readable and haven't been able to change it. It seems I need to be root or hdfs user (su hdfs -) but it asks me for a password which I don't know.

解决方案

A network configuration is not your problem. You don't need to touch any configurations in the VM, you need to start the services. In this image, for example. The HDFS service on the left is disabled, and I get the same error on that last command.

You have to start Cloudera Manager and start ZooKeeper, YARN, and HDFS (in that order).

To open Cloudera Manager, go to http://quickstart.cloudera:7180 in Firefox on the VM.

Then start the mentioned services.

After you start the services, you can use HDFS commands.
