Hi guys, In a nutshell: does Spark check and respect user privileges when reading/writing data.
I am curious about the data security when Spark runs on top of HDFS — maybe though YARN. Is Spark running it's long-running JVM processes as a Spark user, that makes no distinction when accessing data? So is there a shortcoming when using Spark because the JVM processes are already running and therefore the launching user is omitted by Spark when accessing data residing on HDFS? Or is Spark only reading/writing data, that the user had access to, that launched this Thread? What about local store when running in Standalone mode? What about access calls to HBase or Hive then? Thanks for taking time. Best regards, Daniel. --------------------------------------------------------------------- To unsubscribe, e-mail: user-unsubscr...@spark.apache.org For additional commands, e-mail: user-h...@spark.apache.org
