CDH HBase Support¶
This specification proposes to add HBase support for CDH Plugin in Sahara.
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.
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
Data model impact¶
REST API impact¶
Other end user impact¶
The end users need to select HMaster and HRegion process in node group templates.
It will be required to install the necessary HBase package in the cdh image.
Sahara-dashboard / Horizon impact¶
- Primary assignee:
- Other contributors:
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
Zookeeper process must be installed first in the cluster. HBase needs to use Zookeeper service.
Writing Unit Tests to basically test the configuration. It also required to have an integration test with the cluster creation.
Add HBase in the list and add more information about the configuration.
