Den 18:e november förra året lyfte rymdfarkosten Maven från jorden på väg på sitt mål Mars och nu har den äntligen kommit dit och lyckats lägga sig i omloppsbana runt planeten. Maven kommer att bli den första farkosten från jorden, och sannolikt den första från någon annan planet, som kommer att kretsa runt Mars för att studera planetens övre atmosfär. Genom dessa studier Here in this Maven-built Java 8 project you can see all the details that are necessary to make this work out of the box. For instance, I have figured out the necessary pom file dependencies that work with the latest release of the Parquet libraries, parquet-hadoop and parquet-avro.
