Integrate Apache Ranger with Hive, HDFS, Presto, Tagsync from Apache Atlas etc What you'll learn: Apache Ranger Components & ArchitectureComplete Ranger Hive Integration with real usecasesUnderstanding end-to-end Ranger Hive, HDFS, Presto PluginRanger Tag-sync from Apache Atlas What do you Learn From this Course ?In this course, we study end-to-end Apache Ranger authorisation policies and integration with Hadoop components like Hive, HDFS, Apache Atlas, Presto etc.First we learn Ranger Components and Architecture. Next, we install Apache Ranger 2.1.0 which is the latest stable version. Ranger installation looks pretty straightforward. However, ranger requires Solr and Mysql infrastructure. Ranger supports Mysql version 5.6 or 5.7. It won't support beyond these versions. These constraints complicates ranger installation. I spent many days while installing ranger. I consolidated all the steps into a single shell script. Users can download it and run it as it is without any issues. After that, we navigate to apache ranger user interface and explore salient features.In the 3rd section, we achieve Ranger Hive integration. At first, we acquire hive cluster and install ranger hive plugin. We load sample data into hive. We define policies on apache ranger for different users and validate the policies by querying on hive. We also examine Masking and Row Level Filters.In the 4th section, we dig deeper into Ranger HDFS integration. At first, we acquire hive cluster and install HDFS ranger plugin. We dig deeper into the hive Managed Tables and load sample data into HDFS. Lastly, we define HDFS policies and verify it by querying on hive tables.
