1. Release Notes Ambari - 2.6RELEASE NOTES: Apache Ambari 2.6

The Ambari 2.6 Release Notes summarize and describe the following information releasedin Ambari 2.6:

• New Features [1]

• Behavioral Changes [1]

• Patch Information [3]

• Known Issues [4]

• Fixed Issues [5]

1.1. New FeaturesThe Ambari 2.6 release includes the following new features:

Table 1.1. Core Ambari

Feature Description

Ambari Metrics System - Distributedmode with multiple Collectors (GeneralAvailability)


The Ambari Metrics System now supports multiple Metrics Collector instances,providing High Availability and better scalability.

AMS High Availability

Solr Data Manager script to easily delete,archive, or save index data


The Solr Data Manage script allows operators to easily archive and purge logs andaudit data stored in the Ambari Infra Solr Instance.

Archiving and Purging Data

1.2. Behavioral ChangesAmbari 2.6 introduces the following change in behavior as compared to previous Ambariversions:

Ambari Blueprint Stack & Repository Version Behavior Change

In Ambari 2.6.0, the Ambari upgrade framework has been updated to set the stage forautomated patch application and management. This feature will be available in futureversions of Ambari. Due to these changes, the logic used to identify the repo versionto be used during a Blueprint install has changed. This change only impacts Blueprintdeployments. To ensure that Ambari uses the intended version of the repository for yourinstall it’s recommended first to register the desired version of HDP using a VDF file, andsecond to specify the version in your Blueprint explicitly.

If you do not register a VDF file and specify the repository_version_id, or repository_versionduring blueprint creation, Ambari uses the default repository version defined in the stackversions included with Ambari 2.6.0. Ambari identifies the default repository version usingthe hdp_urlinfo.json’s "latest-vdf" if that is available and defined. Otherwise, Ambari uses

Page 6: Hortonworks Data Platform - Apache Ambari Release Notes

Hortonworks Data Platform October 30, 2017


the stack metainfo.xml to identify the default repository version based on the stack_versiondefined in your Blueprint.

To register a VDF file and specify the repository_version_id, or repository_version duringblueprint creation:

Registering a VDF file

The version_definitions API should be used when registering a VDF file. The examplecommand below shows how to register the version of HDP using the publiclyavailable VDF file:

curl -v -k -u admin:admin -H "X-Requested-By:ambari" -X POSThttp://ambari.server:8080/api/v1/version_definitions \-d '{ "VersionDefinition": { "version_url":"http://public-repo-1.hortonworks.com/HDP/centos6/2.x/updates/" } }'

If the publicly available VDF file is not reachable from your installation, you can use a VDFfile that has been downloaded to the local file system of the Ambari Server:

>curl -v -k -u admin:admin -H "X-Requested-By:ambari" -X POSThttp://ambari.server:8080/api/v1/version_definitions \-d '{ "VersionDefinition": { "version_url": "file:/tmp/HDP-" }}'

The response from this request will give you a unique id for the version that has beenregistered. For example:

{ "resources" : [ { "href" :"http://ambari.server:8080/api/v1/version_definitions/51", "VersionDefinition" : { "id" : 51, "stack_name" : "HDP", "stack_version" : "2.6" } } ]}

Specifying Registered Versions in Blueprint Cluster Creation

When using a Blueprint, to ensure the cluster install uses the version referenced in thepreviously registered VDF, either reference the id, or the specific version in the clustercreation request.

Blueprint repository version reference by id:

Page 7: Hortonworks Data Platform - Apache Ambari Release Notes

Hortonworks Data Platform October 30, 2017


...{ "blueprint": "<blueprint name>", "repository_version_id": 1, "default_password": "password", "host_groups": [ ... ]}...

Blueprint repository version reference by version:

...{ "blueprint": "<blueprint name>", "repository_version": "", "default_password": "password", "host_groups": [ ... ]}


Specifying registered versions when pre-installing from local yum repositories

A local repository configured from a yum repository is not "managed" by Ambari.

With Ambari 2.6, a custom yum repo file name (HDP-2.x.x.x.repo) does not have to matchthe Ambari yum repo file name (ambari-hdp-1.repo), but the format of the repo namesin the yum repo file changes. For example, the following repo name format is no longerrecognized by Ambari,

[HDP-] name=HDP Version - HDP-

and has to be changed to the repo name format which Ambari 2.6.x now expects,

[HDP-2.6-repo-1] name=HDP-2.6-repo-1

and which the Ambari install wizard local repo option uses when it creates the ambari-hdp-1.repo file.

IF you are pre-installing HDP packages using a local yum repository, make sure that thelocal repository name is recognized by Ambari-2.6.x.

1.3. Patch InformationAmbari 2.6 is based on Apache Ambari and the following patches.
