Comment 8 for bug 1417962

To expand on comment 6 from @amir what is currently broken for Big Data clusters is the following.

Most Big Data workloads such as setting up a Hadoop Cluster require Java at many levels. Juju[0] has encapsulated the deployment of Big Data workloads like deploying a Hadoop Cluster into Charms. In those charms jps is used in the deployment of Hadoop. A user recently posted to the Juju mailing list the charms failed to deploy a 10 node hadoop cluster[1].

This is a good example of the failure we are seeing. The effect is severe in that anybody deploying a Hadoop Cluster using the current Ubuntu OpenJDK from the archive will hit this failure. The work around isn't that trivial as it requires manual intervention in the connections between services.

If there is any information we can provide to help in the debug of this issue please let us know.
