还没有跳到其他地方已经停止了安装工作。 can not find log file 只能成功安装 JournalNode，并且在查看zookeeper时，出现经常报错，得等待很长时间才能安装成功。
What you expected to happen
安装zkfc失败后，没有namenode，无法安装yarn，导致后续一大堆组件无法安装。希望可以通过官方安装，正确引导下安装成功hdfs及后续的组件。
How to reproduce
按照官方流程，正常搭建服务后，出现此类情况。
Anything else
每次在搭建时都会出现。

这看起来是你的操作系统不支持安装zkfc 你好，我这边运行的linux版本为：Linux version 3.10.0-1160.el7.x86_64 ([email protected]) (gcc version 4.8.5 20150623 (Red Hat 4.8.5-39) (GCC) ) #1 SMP Tue Aug 18 14:50:17 EDT 2020，操作系统的版本为Red Hat Enterprise Linux Server release 7.9 (Maipo)，请问有什么改进的建议么
这是我的日志： zkfc 依然没有正常启动

请问上述问题是否有得到解决，我用麒麟V10 X86服务器搭建的DataSophon也出现了这样的问题 我将会在新版本增加zkfc和namenode强制格式化，来避免此错误发生，来避免zkfc格式化失败，建议先手动清理zookeeper中存储的zkfc信息，手动清理namenode的存储目录，然后重新安装hdfs，
初始化zkfc时 报错HadoopIllegalArgumentException: HA is not enabled for this
有哪位大佬遇到

我将zookeeper,hadoop,hdfs文件夹都删除了，还是不行
