Spark Authorizer

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.

Quick Start

Step 1. Install Spark Authorizer

Include this package in your Spark Applications using:

spark-shell, pyspark, or spark-submit

> $SPARK_HOME/bin/spark-shell --packages yaooqinn:spark-authorizer:2.1.1

sbt

If 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"

Maven

In your pom.xml, add:

<dependencies>
  <!-- list of dependencies -->
  <dependency>
    <groupId>yaooqinn</groupId>
    <artifactId>spark-authorizer</artifactId>
    <version>2.1.1</version>
  </dependency>
</dependencies>
<repositories>
  <!-- list of other repositories -->
  <repository>
    <id>SparkPackagesRepo</id>
    <url>http://dl.bintray.com/spark-packages/maven</url>
  </repository>
</repositories>

Manully

If you Building Spark Authorizer manully, you can deploy via:

cp target/spark-authorizer-<version>.jar $SPARK_HOME/jars

Step 2. Install & Configure Ranger Hive Plugin

Please 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.

Step 3. Enable Spark Authorizer

In $SPARK_HOME/conf/spark-defaults.conf, add:

spark.sql.extensions=org.apache.ranger.authorization.spark.authorizer.RangerSparkSQLExtension

NOTE 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.

Interactive Spark Shell

The easiest way to start using Spark is through the Scala shell:

bin/spark-shell --master yarn --proxy-user hzyaoqin

Suffer for the Authorization Pain

We create a ranger policy as below:

Check Privilege with some simple cases.

Show databases

scala> spark.sql("show databases").show

scala> spark.sql("use spark_test_db").show
