Spark Authorizer provides you with SQL Standard Based Authorization for Apache Spark™ as same as SQL Standard Based Hive Authorization. While you are using Spark SQL or Dataset/DataFrame API to load data from tables embedded with Apache Hive™ metastore, this library provides row/column level fine-grained access controls by Apache Ranger™ or Hive SQL Standard Based Authorization.
Security is one of fundamental features for enterprise adoption. Apache Ranger™ offers many security plugins for many Hadoop ecosystem components, such as HDFS, Hive, HBase, Solr and Sqoop2. However, Apache Spark™ is not counted in yet. When a secured HDFS cluster is used as a data warehouse accessed by various users and groups via different applications wrote by Spark and Hive, it is very difficult to guarantee data management in a consistent way. Apache Spark users visit data warehouse only with Storage based access controls offered by HDFS. This library shares Ranger Hive plugin with Hive to help Spark talking to Ranger Admin.
Please refer to ACL Management for Spark SQL to see what spark-authorizer supports.
Include this package in your Spark Applications using:
> $SPARK_HOME/bin/spark-shell --packages yaooqinn:spark-authorizer:2.1.1If you use the sbt-spark-package plugin, in your sbt build file, add:
spDependencies += "yaooqinn/spark-authorizer:2.1.1"
Otherwise,
resolvers += "Spark Packages Repo" at "http://dl.bintray.com/spark-packages/maven"
libraryDependencies += "yaooqinn" % "spark-authorizer" % "2.1.1"
In your pom.xml, add:

cp target/spark-authorizer-<version>.jar $SPARK_HOME/jarsPlease refer to Install Ranger Hive Plugin For Apache Spark to learn how to deploy the plugin jars to Apache Spark and set Ranger/Hive configurations.
In $SPARK_HOME/conf/spark-defaults.conf, add:
spark.sql.extensions=org.apache.ranger.authorization.spark.authorizer.RangerSparkSQLExtensionNOTE spark.sql.extensions is only supported by Spark 2.2.x and later, for Spark 2.1.x please use Version: 1.1.3.spark2.1 and check the previous doc.
The easiest way to start using Spark is through the Scala shell:
bin/spark-shell --master yarn --proxy-user hzyaoqinWe create a ranger policy as below:
