No, because this is a storage concept, and Spark is not a storage system. You would appeal to tools and interfaces that the storage system provides, like hdfs. Where or how the hdfs binary is available depends on how you deploy Spark where; it would be available on a Hadoop cluster. It's just not a Spark question.

In Zeppelin/Spark, the hdfs executable is not accessible. As a result, I wondered if there was a class in Spark (eg. Security or ACL) which would let you access a particular user's groups. ----- Mail original ----- De: "Sean Owen" < sro...@gmail.com > À: phi...@free.fr Cc: "User" < user@spark.apache.org > Envoyé: Mercredi 7 Septembre 2022 16:41:01 Objet: Re: Spark equivalent to hdfs groups Spark isn't a storage system or user management system; no there is no notion of groups (groups for what?)
