Updated CDH Components

CDH Component Changes in Cloudera Private Cloud Base 7.

Component Changes in Cloudera Private Cloud Base 7.0

Pig, Flume, Sentry, and Navigator have been removed.

  • Pig can be replaced with Hive or Spark.

  • Flume has been replaced with Cloudera Flow Management (CFM). CFM is a no-code data ingestion and management solution powered by Apache NiFi. Contact your Cloudera account team for more information about moving from Flume to CFM.

  • Sentry has been replaced with Apache Ranger. A Sentry-to-Ranger policy migration tool is available for Cloudera Private Cloud Base 7.1 and migrations will be supported when Replication Manager is used to migrate Hive tables from CDH to CDP.

  • Navigator has been replaced with Apache Atlas.

  • Cloudera Director is not supported with Cloudera Private Cloud Base.
  • MapReduce v1 was deprecated as of CDH 5.0 and is not supported in CDP.

Component Changes in Cloudera Private Cloud Base 7.1

  • The YARN Fair Scheduler is being replaced with the YARN Capacity Scheduler. A migration tool will be provided to convert the Fair Scheduler configurations to Capacity Scheduler.

  • The Sentry policy files feature option has been deprecated in CDH 5.x and is entirely removed in Cloudera Private Cloud Base 7.1. Prior to an upgrade to Cloudera Private Cloud Base 7.1, the Sentry Service role must be set up and used for enforcing access policies over Hive/Solr. To migrate the existing Sentry Policy file configuration to a Sentry Service, see: Migrating from Sentry Policy Files to the Sentry Service .
  • Navigator has been replaced with Apache Atlas.

    Navigator lineage data can be transferred to Atlas as part of the CDH to Cloudera Private Cloud Base upgrade process. Navigator audit data is not transferred to Atlas.

    When you upgrade a CDH cluster to Cloudera Private Cloud Base, the Navigator audits persist. However, services no longer produce audits for Navigator. You can continue to run Navigator to be able to access the audits. See Transitioning Navigator audits.

The following CDH components have been included in Cloudera Runtime for the first time in Cloudera Private Cloud Base 7.1.1.

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:
