This quick demo illustrates how easy it is to implement role-based access and control in Impala using Sentry.
Apache Sentry (incubating) is the Apache Hadoop ecosystem tool for role-based access control (RBAC). In this how-to, I will demonstrate how to implement Sentry for RBAC in Impala. I feel this introduction is best motivated by a use case.
Data warehouse optimization is one of the most common Hadoop use cases.
Sure, Spark is fast, but it also gives developers a positive experience they won’t soon forget.
Apache Spark is well known today for its performance benefits over MapReduce, as well as its versatility. However, another important benefit – the elegance of the development experience – gets less mainstream attention.
In this post, you’ll learn just a few of the features in Spark that make development purely a pleasure.
