This docker can be used as a sandbox for testing flamy. It is required to run the second part of flamy's demo.

Run this command to build the docker image (might require sudo rights)

docker build -t docker-hive-spark .

Then run this from the flamy-demo repository's base directory

docker run --rm -e USER=`id -u -n` -e USER_ID=`id -u` -it -v `pwd`/data:/data/hive -p 127.0.0.1:9083:9083 -p 127.0.0.1:4040:4040 -p 127.0.0.1:10000:10000 docker-hive-spark

It will start a docker that will automatically:

• expose a running Metastore on the port 9083
• expose a running Spark ThriftServer (similar to HiveServer2) on port 10000
• expose the Spark GUI to follow job progress on port 4040
• start a beeline terminal

In case you wonder what the part with the USER and USER_ID is about: it is a kind of docker-voodoo-danse to prevent docker writing stuff as root in the external volume.

This docker has Hive and Spark preconfigured to support Hive tables on Amazon s3. You must pass your credentials to the docker by adding these options to the above docker run command. Of course you shall replace the dots with the correct values.

-e AWS_ACCESS_KEY_ID=... -e AWS_SECRET_ACCESS_KEY=...

Next, you can create a table with

CREATE EXTERNAL TABLE my_db.mytable (columns ...) 
LOCATION "s3a://my_bucket/my/table/path"

Please note the EXTERNAL keyword which is highly recommended if you don't want to lose the data when the table is dropped (s3 doesn't implemented hdfs's Trash...). Please also note that the location starts with s3a, and not s3 or s3n.
