This post is about location awareness in Kudu. It gives an overview of the following:

• principles of the design
• restrictions of the current implementation
• potential future enhancements and extensions

Note: This is a cross-post from the Cloudera Engineering Blog Fine-Grained Authorization with Apache Kudu and Impala

Apache Impala supports fine-grained authorization via Apache Sentry on all of the tables it manages including Apache Kudu tables. Given Impala is a very common way to access the data stored in Kudu, this capability allows users deploying Impala and Kudu to fully secure the Kudu data in multi-tenant clusters even though Kudu does not yet have native fine-grained authorization of its own. This solution works because Kudu natively supports coarse-grained (all or nothing) authorization which enables blocking all access to Kudu directly except for the impala user and an optional whitelist of other trusted users. This post will describe how to use Apache Impala’s fine-grained authorization support along with Apache Kudu’s coarse-grained authorization to achieve a secure multi-tenant deployment.

Note: This is a cross-post from the Cloudera Engineering Blog Testing Apache Kudu Applications on the JVM

Although the Kudu server is written in C++ for performance and efficiency, developers can write client applications in C++, Java, or Python. To make it easier for Java developers to create reliable client applications, we’ve added new utilities in Kudu 1.9.0 that allow you to write tests using a Kudu cluster without needing to build Kudu yourself, without any knowledge of C++, and without any complicated coordination around starting and stopping Kudu clusters for each test. This post describes how the new testing utilities work and how you can use them in your application tests.
