> We've come to a point where our tests need to have a uniform way of
> interfacing with the cluster under test. It is no longer ok to assume that
> the test can be executed on a particular node (and thus have access to
> services running on it). It is also less than ideal for tests to assume a
> particular type of interaction with the services since it tends to break in
> different deployment scenarios.
> A framework that needs to be put in place has to be capable of (regardless of
> where a test using it is executed on):
> # representing the abstract configuration of the cluster
> # representing the abstract topology of the entire cluster (services
> running on a cluster, nodes hosting the daemons, racks, etc).
> # giving tests an ability to query this topology
> # giving tests an ability to affect the nodes in that topology in a
> particular way (refreshing configuration, restarting services, etc.)
> Of course, the ideal solution here would be to give Bigtop tests a
> programmatic access to a Hadoop cluster management framework such as
> Cloudera's CM or Apache Ambari.
> As with any ideal solutions I don't think it is realistic though. Hence we
> have to cook something up. At this point I'm really focused on getting the
> API right and I'm totally fine with an implementation of that API to be
> something as silly as a bunch of ssh-based scripts or something.
> This JIRA is primarily focused on coming up with such an API. Anybody who's
> willing to help is welcome to.
