A quickstart demo to showcase Hudi functionalities using docker along with support for integration-tests #455

bvaradar · 2018-09-11T13:23:13Z

Comes with foundations for adding docker integration tests. Docker images built with Hadoop 2.8.4 Hive 2.3.3 and Spark 2.3.1

Demo using docker containers with documentation

@sungjuly @n3nash : Thanks a lot for providing the feedback. I have revamped this PR and made few improvements. Here is the list:

Reimplement docker files to reduce image sizes. I am seeing 3-4x improvements in docker sizes (from 4 - 5 GB to 0.8-1.5GB).
I have published all the docker images to docker-hub (temporarily using my docker-hub account) so that there is no need to build the docker images as part of running the script.
Made both docker images and compose follow convention so that a single image can satisfy both use-cases
(a) Standalone - Docker images that are published to Docker-hub have inbuilt hudi jars so that they are self-contained.
(b) Mounting Convention - The images allow for overriding those hudi jars with locally built jars allowing for the same setup to be used for running integ-testing against code-changes locally (look at the compose script and hoodie-integ/pom.xml)
Updates quickstart docs to reflect the changes above

I have marked this PR as WIP since I need to showcase incremental view as part of demo.

@n3nash @sungjuly : Can you please follow the quickstart steps and let me know your experience.
Our aim is to have an easy-to-use and hassle-free hudi quickstart. I would appreciate your feedback on that.

I've encountered this. It seems it's related docker version. Here's my env to figure out problems.

docker-engine: 18.06.1-ce (there's no way to downgrade 17.12 since the official site only supports the latest version for Mac)

docker-compose: 1.22.0

The container name "/kafkabroker" is alreCreating hive-metastore-postgresql ... error ame) that container to be able to reuse that name.

@sungjuly : ok, can you check "docker container ls" and see if there are stopped/running containers with the same name. If you find them, can you remove the containers using "docker rm".

This is an one-time issue for those who tried this PR before. I have moved the compose script to a different file but the container names are same. Removing the docker containers should hopefully fix the issue.

For a different reason, I reverted my docker (mac) installation to "factory defaults" and that also fixed the problem.

docker env was cleaned up all things before I tested. Here's output for docker container ls

➜ docker git:(docker) ✗ docker container ls CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES

It worked after resetting to factory defaults on docker! thank you! @bvaradar

this is now hoodie-utilities-0.4.4-SNAPSHOT.jar with the new release. same comment on other 3 occurrances as well.. Can we name the jar differently inside the container without the version? that way it will continue to work? (I understand it takes away knowing what version is being tested.) thoughts?

Also DeltaStreamer now takes a --storage-type COPY_ON_WRITE/MERGE_ON_READ argument which is required.. we can use this and get rid of steps to create the dataset manually via CLI? DeltaStreamer will create the dataset if the basePath does not exist.

@vinothchandar : I have made changes to treat hoodie-utilities jar in the same was as other bundle jars. The utilities jar will now be part of docker image with version removed. It is also available using the alias $HUDI_UTILITIES_BUNDLE. I have updated quickstart and uploaded newer docker images with "latest" tag so you should see the changes when you setup demo again. The 2nd step of explicitly initializing Hudi datasets using Hudi CLI is also removed.

@bvaradar docker/compose#3574 don't think compose up will pull in latest images.. I am going remove all containers and retry.. We probably need to have a better support in the script for optionally also doing a compose pull before?

That worked @bvaradar .. One more issue I found was between recreating containers, the path on host machine /tmp/hadoop* needs to be blown away.. Can we add a rm -rf before the mkdir -p in the setup script.. other than that, verified that building and deltastreamer work..

add a protective rm -rf here? otherwise NN will start in safe mode since it does not recognize the data

once the docker containers are stopped, the files are deleted using "rm -rf ". I did not want to do the deletion before docker compose down so that docker containers can be shutdown more cleanly. Will chat f2f to explain more.
