This project builds a Docker container from which you can use impala-shell.
You will need to have installed Docker.
Start running the built container image with:
docker run -it --rm jimdigriz/impala-shell
This will drop you straight into a CLI REPL similar to {sqlite3,mysql,psql}.
If you want to use this from a script, you may find the following form useful to run queries directly:
docker run --rm jimdigriz/impala-shell -i impala.example.com -q 'SELECT 1 AS test'
Before using the REPL, you will need to authenticate to Kerberos from your own workstations (apt-get install krb5-user):
env KRB5CCNAME=DIR:.krb5cc kinit bob@EXAMPLE.COM
Now use the REPL instead via:
docker run -it --rm --env KRB5CCNAME=DIR:/tmp/krb5cc -v $(pwd)/.krb5cc:/tmp/krb5cc:ro jimdigriz/impala-shell
Make sure you have above 15GiB of disk space free avaliable to Docker (df -h /var/lib/docker) and then checkout a copy of the project with:
git clone https://gitlab.com/jimdigriz/impala-shell.git
cd impala-shell
Now build the container, which will take 20 minutes on a 50Mbps Internet connection; most of that time is spent in downloading content:
docker build -t impala-shell .
To push up to Docker Hub:
docker tag impala-shell:latest jimdigriz/impala-shell:latest
docker push jimdigriz/impala-shell:latest
