CDH HBase Support

CDH HBase Support

https://blueprints.launchpad.net/sahara/+spec/cdh-hbase-support

This specification proposes to add HBase support for CDH Plugin in Sahara.

Problem description

There is no HBase support in current cdh plugin, but Cloudera Manager supports to install this service in a cluster. HBase is a non-relational, distributed database model and can provide BigTable-like capabilities for Hadoop. This service should be supported in Sahara cdh plugin.

Proposed change

The implementation will support CDH 5.0.0. Support Features:

  • Install HBase processes in a CDH cluster using cm-api
  • Zookeeper must be selected and launched in a cluster first
  • Support HMaster and Multiple HRegion processes in a cluster
  • Most Configuration Parameters Support in a CDH cluster

Alternatives

None

Data model impact

None

REST API impact

None

Other end user impact

The end users need to select HMaster and HRegion process in node group templates.

Deployer impact

None

Developer impact

None

Sahara-image-elements impact

It will be required to install the necessary HBase package in the cdh image.

Sahara-dashboard / Horizon impact

None

Work Items

The work items can be divided to several parts:

  • Investigate HBase service in a CDH cluster via Cloudera Manager(CM)
  • Leverage CM-API Client to call functions to install Zookeep via CM
  • Test and Evaluate the Concept
  • Implement Source Code in Sahara cdh plugin
  • Test the Code

Dependencies

Zookeeper process must be installed first in the cluster. HBase needs to use Zookeeper service.

Testing

Writing Unit Tests to basically test the configuration. It also required to have an integration test with the cluster creation.

Documentation Impact

Add HBase in the list and add more information about the configuration.
