Yarnpkg和Hadoop Yarn命名冲突

Posted on 2016-11-30 Disqus:

如果同时安装了Yarn和Hadoop，那么在你运行yarnpkg命令时，如

1	yarn --version

你会发现这个诡异问题

1
2
3

Unrecognized option: --version
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.

因为它和Hadoop Yarn名字重复了，而两者都在PATH里。Github上也有这个Issue，有人在备注里提议改名为nyarn，但是没有采纳，而是给了一个yarnpkg的别名…
