What works:
* A single node cluster can be started up with docker-compose
* HMS data is stored in Derby database in a docker volume
* Filesystem data is stored in a shared docker volume, using the
localfs support in the Hadoop client.
* A Kudu cluster with a single master can be optionally added on
to the Impala cluster.
* TPC-DS data can be loaded automatically by a data loading container.
We need to set up a docker network called quickstart-network,
purely because docker-compose insists on generating network names
with underscores, which are part of the FQDN and end up causing
problems with Java's URL parsing, which rejects these technically
invalid domain names.
How to run:
Instructions for running the quickstart cluster are in
docker/README.md.
How to build containers:
./buildall.sh -release -noclean -notests -ninja
ninja quickstart_hms_image quickstart_client_image docker_images
How to upload containers to dockerhub:
IMPALA_QUICKSTART_IMAGE_PREFIX=timgarmstrong/
for i in impalad_coord_exec impalad_coordinator statestored \
impalad_executor catalogd impala_quickstart_client \
impala_quickstart_hms
do
docker tag $i ${IMPALA_QUICKSTART_IMAGE_PREFIX}$i
docker push ${IMPALA_QUICKSTART_IMAGE_PREFIX}$i
done
I pushed containers build from commit f260cce22, which
was branched from 6cb7cecacf on master.
Misc other stuff:
* Added more metadata to all images.
TODO:
* Test and instructions to run against Kudu quickstart
* Upload latest version of containers before merging.
