cloudera CDP is based on a Cloudera Runtime Version + a Cloudera Manager version that is compatible (with that cloudera runtime)   https://docs.cloudera.com/cdpdc/7.0/release-guide/topics/cdpdc-release-notes-links.html   at time of writing: CDP DC 1.0 uses Cloudera runtime 7.0.3 and cloudera manager 7.0.3   the Cloudera Runtime Component Version is aimed to keep a set of consistent hadoop components versions that can work together. it will also make more easy to migrate from CDH/HDP if services/components versions are the same or close to the runtime components versions of CDP   if i'm not wrong, there is actually only one CDP DC (1.0) version with minor updates of CM and cloudera components runtime versions   https://docs.cloudera.com/cloudera-manager/7.0.3/release-notes/topics/cm-release-notes.html https://docs.cloudera.com/runtime/7.0.3/release-notes/topics/rt-runtime-component-versions.html       ...
