Cloudera uses the following versioning convention: major.minor.maintenance. If a cluster runs Cloudera Manager 5.14.0, the major version is 5; the minor version is 14; and the maintenance version is 0.
The Cloudera Manager minor version must always be equal to or greater than the CDH minor version. Older versions of Cloudera Manager might not support features in newer versions of CDH.
For example, Cloudera Manager 5.12.0 can manage CDH 5.12.2 because the minor versions are equal. Cloudera Manager 5.12.0 cannot manage CDH 5.14.0 because the Cloudera Manager minor version, 12, is less than the CDH minor version, 14.
Important: Using Cloudera Manager 6.0.x to manage a CDH 5.15.x or CDH 5.16 cluster is not a supported configuration.
