问题描述

我想将2.4.1升级到2.6稳定版本.就像用最新的文件夹内容替换所有文件夹内容一样简单吗?

I want to upgrade 2.4.1 to 2.6 stable version. Is it as simple as replacing all the folder contents with the latest ones?

推荐答案

如果停机时间不成问题，只需关闭集群(bin/stop-dfs.sh)，使用hadoop-2.6解压缩存档，复制您要配置的配置文件. ve在2.4.1中更改为2.6，更改hadoop链接，以使其现在链接到新的hadoop-2.6文件夹，然后运行以下命令:

If the downtime is not an issue, just shut down the cluster (bin/stop-dfs.sh), unzip the archive with hadoop-2.6, copy configuration files that you've changed in 2.4.1 into 2.6, change the hadoop link so that it's now linked to the new hadoop-2.6 folder and run this command:

bin/start-dfs.sh -upgrade

此后，群集应启动并正常工作.

After this the cluster should be started and working.
