我有五台服务器，免费CDH4安装在它们上，服务运行良好。今天，我想添加两个主机，但是失败了。
这是日志。

这不是真正的问题。在下一个命令中，您会看到!
Installing oracle-j2sdk1.6 package...
BEGIN sudo apt-cache show oracle-j2sdk1.6
E: No packages found
END (100)
remote package oracle-j2sdk1.6 is not available, giving up
然后执行回滚。
我认为真正的问题是安装oracle-j2sdk1.6，但我不知道如何解决。
谢谢。
最佳答案
我手动安装oracle-j2sdk1.6并完成安装。如果您所在的国家不抵制，您将不会看到此错误。
