Motivations

At this time, using the Apache Parquet Tools CLI requires either:

  • downloading a pre-built JAR file from a public Maven repository. But, as far as I know, only the Hadoop mode is built, which means that the Hadoop client dependency is not included in the JAR;
  • or building it manually, for example if you need a version not released yet. Building it however requires few operations and dependencies that can easily fit into a Dockerfile, so as to be reusable elsewhere.

This repository provides a quite simple public Docker image that builds the Apache Parquet Tools CLI for both Local and Hadoop modes. In the end, the Docker image allows to use the CLI in a quite straightfoward manner.

Example Usage

docker container run -v /tmp/data:/data --rm -t rm3l/parquet-tools:latest schema /data/<myFile>.parquet
