Description

There's been past discussion on running Hadoop client and service code in OSGi. This JIRA issue exists to wrap up the needs and issues.

1. client-side use of public Hadoop APIs would seem most important.
2. service-side deployments could offer benefits. The non-standard Hadoop Java security configuration may interfere with this goal.
3. testing would all be functional with dependencies on external services, to make things harder.
