While installing the CDH parcel, we have to ensure the Cloudera Manager and CDH compatibility. Cloudera version is having 3 parts – … Cloudera Manager major and minor version must be the same as CDH major and minor version.
For Example, we are using Cloudera Manager 6.3.1 and CDH 6.3.2. Here 6 is major and 3 is the minor version. Major and Minor must be the same to avoid compatibility issues.
