This page lists operating systems, Java versions, databases, platforms, CDH components and subcomponents, and product functionality that have been deprecated or removed.
Deprecated Items
A deprecated item is a feature, component, platform, or functionality that Cloudera is planning to remove in a future release. Cloudera supports items that are deprecated until they are removed, and the deprecation gives customers time to plan for removal.
The following table lists deprecated items:

|---|---|---|---|
| Activity Monitor | Activity Monitor is only used and deployed by Cloudera Manager when the MapReduce service (MRv1) is deployed. | 5.9.0 | 7.0.0 |
