             Summary: refresh juju spark-processing bundle
                 Key: BIGTOP-2617
                 URL: https://issues.apache.org/jira/browse/BIGTOP-2617
             Project: Bigtop
          Issue Type: Improvement
          Components: deployment
    Affects Versions: 1.1.0
            Reporter: Kevin W Monroe
            Assignee: Kevin W Monroe
            Priority: Minor


Similar to #2616, we've made improvements to the spark-processing bundle that 
are ready for review and inclusion upstream:

- refresh bundled charms, including the use of bigtop-zookeeper
- reduce spark machine count (2 units instead of 3, which still allows HA 
without as much $$$ in cloud resources)
- ganglia/rsyslog have been updated from trusty to xenial
- add new machine constraints since aws now defaults to an 8gb root disk (we 
want 32g at a minimum)
- run the bigtop smoke tests for spark/zookeeper
- ensure the proper amulet test harness is included in the bundle tests
