Hi, DataFusion is a component which is an in-memory query engine using Apache Arrow as the memory model.
I have created a Dockerfile for DataFusion (https://issues.apache.org/jira/browse/ARROW-4467) for it. In order to help user to start using DataFusion for some simple real world use cases, I would like to publish a docker image with tag 'apache/arrow-datafusion' to the DockerHub. What's the procedure to publish a docker image to DockerHub prefixed with apache? Cheers, Zhiyuan
