<p>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.</p>

<p>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.</p>

<p>When picking a storage option for an application it is common to pick a single
storage option which has the most applicable features to your use case. For mutability
and real-time analytics workloads you may want to use Apache Kudu, but for massive
scalability at a low cost you may want to use HDFS. For that reason, there is a need
for a solution that allows you to leverage the best features of multiple storage
options. This post describes the sliding window pattern using Apache Impala with data
stored in Apache Kudu and Apache HDFS. With this pattern you get all of the benefits
of multiple storage layers in a way that is transparent to users.</p>
