Smoke Tests

Setup repo

Bigtop release repo doesn't have arm64 support. To execute smoke test it is required to setup local repo with packages we build out.

docker run -v `pwd`:/ws bigtop/slaves:erp17.08-debian-8-aarch64 bash -l -c 'cd /ws ; ./gradlew apt'

Create test configuration

Bigtop smoke test uses yaml to configure test repo/environment/components. A typical configuration yaml can be found at <BIGTOP_SRC_TOP>/provisioner/docker/erp17.08-debian-8-aarch64

Generally following properties should be customized for certain smoke test:

docker image
repo url
distro type
components to install
components to test

Following is configuration yaml for Hive:

Execute test

It is quite straight forward to execute smoke in bigtop

cd provisioner/docker
./docker-hadoop.sh -C <smoke_test_cfg_yaml> -c <node_count> -s -d

Before running smoke test, it is suggested to run environment check first

./docker-hadoop.sh -E

For detailed usage, just issue: ./docker-hadoop.sh

usage: docker-hadoop.sh [-C file ] args
       -C file                                   Use alternate file for config.yaml
  commands:
       -c NUM_INSTANCES, --create NUM_INSTANCES  Create a Docker based Bigtop Hadoop cluster
       -d, --destroy                             Destroy the cluster
       -e, --exec INSTANCE_NO|INSTANCE_NAME      Execute command on a specific instance. Instance can be specified by name or number.
                                                 For example: docker-hadoop.sh --exec 1 bash
                                                              docker-hadoop.sh --exec docker_bigtop_1 bash
       -E, --env-check                           Check whether required tools has been installed
       -l, --list                                List out container status for the cluster
       -p, --provision                           Deploy configuration changes
       -s, --smoke-tests                         Run Bigtop smoke tests
       -h, --help
