报错日志

报错原因：

根据日志里面的信息，我们可以看出，这个问题肯定和manifest.json这个文件有关系。

这时，我想起来这个文件是CDH一开始安装的时候用到的三个文件之一，后来安装kafka的时候，这个文件被替换了。

CDH-5.15.1-1.cdh5.15.1.p0.4-el7.parcel

CDH-5.15.1-1.cdh5.15.1.p0.4-el7.parcel.sha1

manifest.json

报错解决：

我找到这个目录：/opt/cloudera/parcel-repo/

把以前备份的manifest.json文件放进上面的目录

重启cloudera-scm-server，报错解决。
