Description

This JIRA captures the needed things in order to start hadoop services in OSGi.

The main idea I used so far consists in:

• using the OSGi ConfigAdmin to store the hadoop configuration
• in that configuration, use a few boolean properties to determine which services should be started (nameNode, dataNode ...)
• expose a configured url handler so that the whole OSGi runtime can use urls in hdfs:/xxx
• the use of an OSGi ManagedService means that when the configuration changes, the services will be stopped and restarted with the new configuration
