有没有将节点添加到正在运行的Hadoop集群的方法？ [英] Is there a way to add nodes to a running Hadoop cluster?

问题描述

我一直在玩Cloudera，并在开始工作之前定义了群集的数量，然后使用cloudera管理器确保一切正在运行。

I have been playing with Cloudera and I define the number of clusters before I start my job then use the cloudera manager to make sure everything is running.

我正在开发一个新项目，而不是使用hadoop使用消息队列分发工作，但工作结果存储在HBase中。我可能会启动10台服务器来处理作业并存储到Hbase，但是我想知道如果以后我决定添加更多的工作节点，我可以轻松地（读取：可编程）使它们自动连接到正在运行的群集，以便它们可以本地添加到群集HBase / HDFS？

I’m working on a new project that instead of using hadoop is using message queues to distribute the work but the results of the work are stored in HBase. I might launch 10 servers to process the job and store to Hbase but I’m wondering if I later decided to add a few more worker nodes can I easily (read: programmable) make them automatically connect to the running cluster so they can locally add to clusters HBase/HDFS?

这是可能的，我需要学习什么来完成它？

Is this possible and what would I need to learn in order to do it?

推荐答案

以下是将节点添加到 Hadoop < a>和 HBase 。查看文档，不需要重新启动集群。节点可以动态添加。

Here is the documentation for adding a node to Hadoop and for HBase. Looking at the documentation, there is no need to restart the cluster. A node can be added dynamically.
