Trafodion 2001
This is an initial pull request to validate changes which enable elasticity
changes (JIRA: TRAFODION-2001).
These elasticity changes allow for Trafodion cluster node (hostname)
membership to be changed while the instance is operational. Node can be added
or deleted while the instance is running.
These changes include:
o Implementation of Trafodion Configuration API shared library
- Provides an interface to a repository for Trafodion Configuration and
Registry
+ Initial repository storage method implemented is SQLite
- Allows for future repository storage methods such as Zookeeper, MySQL,
etc. to added without affecting the rest of the Trafodion components
o Implementation of 'PERSIST' configuration section
- A template based persistent process definition
o Implementation of new shell commands (and enhancements to existing
commands):
- node add node-name <node-name>,
cores {<first-core>} [ - <last-core>}],
processors {<processor-count>},
roles {connection|aggregation|storage}
- node config [<nid>|<node-name>]
- node delete <node-name>
- node down <nid>|<node-name> [, <reason-string>]
- node info [<nid>]
- node name <old-node-name> <new-node-name>
- node up <name>
- persist config [{keys}|<persist-process-prefix>]
- persist exec <persist-process-prefix>
- persist info [<persist-process-prefix>]
- persist kill <persist-process-prefix>

> Trafodion Elasticity enhancements
> ---------------------------------
>
> Key: TRAFODION-2001
> URL: https://issues.apache.org/jira/browse/TRAFODION-2001
> Project: Apache Trafodion
> Issue Type: New Feature
> Components: documentation, foundation, installer
> Affects Versions: 2.2-incubating
> Reporter: Gonzalo E Correa
> Assignee: Gonzalo E Correa
> Attachments: TRAFODION-2001-Elasticity.docx,

>
> Abstract
> This JIRA proposes changes to the Apache Trafodion Incubation configuration
> and operational elements used to define and operate a Trafodion cluster in a
> Trafodion instance. The changes proposed build on existing functionality for
> enhancing Trafodion to support elasticity by implementing the ability to add
> and delete nodes used by Trafodion components.
> The concept of a cluster is defined in Trafodion through the configuration of
> nodes in the ‘sqconfig’ text file, the Trafodion configuration file. This
> configuration file is compiled to generate a set of files used to start and
> stop a Trafodion instance. The files generated consist of a configuration
> database and scripts which presently contain fixed, i.e., hardcoded,
> configuration topology attributes of a configured Trafodion instance. This
> proposal addresses this hardcoded configuration topology issue by adding new
> configuration commands in the Trafodion Foundation’s monitor components,
> changing the methodology in the scripts generated, and extending the use of
> the configuration database currently in use.
> Objectives
> The objective of this proposal is to implement elasticity capabilities in
> Trafodion to match or exceed the elasticity capabilities of other modules in
> the Hadoop eco system.
> This focuses on the Trafodion Foundation functionality. Specifically, the
> monitor components which use the configuration of nodes that define a
> Trafodion cluster are enhanced to provide at set of primitive commands to add
> and delete nodes as well as the generation of events to existing processes in
> the instance of the addition or deletion of member nodes to the cluster
> configuration.
