         Apache Accumulo Data Sources

Accumulo data sources use a Teiid specific JCA connector that is deployed into AS 7.2 (EAP 6.1 Alpha) during installation. There are many ways to create a Accumulo data source, using CLI, AdminShell, admin-console, etc. The example shown below uses the CLI tool, as this works in both Standalone and Domain modes.

Execute the following command using the CLI once you connected to the Server. Make sure you provide the correct URL and user credentials. Add any additional properties required by the connector by duplicating the "connection-definitions" command below. Edit the JNDI name to match the JNDI name you used in VDB.

batch
/subsystem=resource-adapters/resource-adapter=accumulo/connection-definitions=teiid:add(jndi-name=java:/accumulo-ds, class-name=org.teiid.resource.adapter.accumulo.AccumuloManagedConnectionFactory, enabled=true, use-java-context=true)
/subsystem=resource-adapters/resource-adapter=accumulo/connection-definitions=teiid/config-properties=ZooKeeperServerList:add(value=localhost:2181)
/subsystem=resource-adapters/resource-adapter=accumulo/connection-definitions=teiid/config-properties=Username:add(value=user)
/subsystem=resource-adapters/resource-adapter=accumulo/connection-definitions=teiid/config-properties=Password:add(value=password)
/subsystem=resource-adapters/resource-adapter=accumulo/connection-definitions=teiid/config-properties=InstanceName:add(value=instancename)
# optional visibility for user, supply multiple with comma separated 
/subsystem=resource-adapters/resource-adapter=accumulo/connection-definitions=teiid/config-properties=Roles:add(value=public)
/subsystem=resource-adapters/resource-adapter=accumulo:activate
runbatch

To find out all the properties that are supported by this Accumulo Connector execute the following command in the CLI.

/subsystem=teiid:read-rar-description(rar-name=accumulo)

Developer's Tip
If the JBoss AS 7.2 (EAP 6.1 Alpha) is running in standalone mode, you can also manually edit the "<jboss-install>/standalone/configuration/standalone-teiid.xml" file and add the XML configuration defined in "<jboss-install>/docs/teiid/datasources/accumulo" directory under "resource-adapters" subsystem. Shutdown the server before you edit this file, and restart after the modifications are done.
