This fixes all core e2e tests running on my local dockerised minicluster build. I do not yet have a CI job or script running but I wanted to get feedback on these changes sooner. The second part of the change will include the CI script and any follow-on fixes required for the exhaustive tests. The following fixes were required: * Detect docker_network from TEST_START_CLUSTER_ARGS * get_webserver_port() does not depend on the caller passing in the default webserver port. It failed previously because it relied on start-impala-cluster.py setting -webserver_port for *all* processes. * Add SkipIf markers for tests that don't make sense or are non-trivial to fix for containerised Impala. * Support loading Impala-lzo plugin from host for tests that depend on it. * Fix some tests that had 'localhost' hardcoded - instead it should be $INTERNAL_LISTEN_HOST, which defaults to localhost. * Fix bug with sorting impala daemons by backend port, which is the same for all dockerised impalads. Testing: I ran tests locally as follows after having set up a docker network and starting other services: ./buildall.sh -noclean -notests -ninja ninja -j $IMPALA_BUILD_THREADS docker_images export TEST_START_CLUSTER_ARGS="--docker_network=impala-cluster" export FE_TEST=false export BE_TEST=false export JDBC_TEST=false export CLUSTER_TEST=false ./bin/run-all-tests.sh Change-Id: Iee86cbd2c4631a014af1e8cef8e1cd523a812755 Reviewed-on: http://gerrit.cloudera.org:8080/12639 Reviewed-by: Joe McDonnell <joemcdonnell@cloudera.com> Tested-by: Impala Public Jenkins <impala-public-jenkins@cloudera.com>
