This is really about testing the dockerised minicluster, but gives us coverage of remote read code paths for free, and more people care about that right now.
I got the core end-to-end tests passing locally as part of https://issues.apache.org/jira/browse/IMPALA-7995. That change is up for review here https://gerrit.cloudera.org/c/12639/. The next step is to get a Jenkins job running, which I've been working on. I'd like to run it regularly so we can catch any regressions. Initially I'll just have it email me when it fails, but after it's stable for a week or two I'd like to make it part of the regular set of jobs. My preference is to run it as part of the precommit jobs, in parallel to the Ubuntu 16.04 tests. It should not extend the critical path of precommit because it only runs the end-to-end tests. We could alternatively run it as a scheduled post-commit job, but that tends to create additional work when it breaks. What do people think? - Tim
