| <p>Cloudera’s CDP Runtime version 7.1.5 maps to Apache Kudu 1.13 and upcoming Apache Impala 4.0</p> |
| |
| <h2 id="introduction">Introduction</h2> |
| <p>In database systems one of the most effective ways to improve performance is to avoid doing |
| unnecessary work, such as network transfers and reading data from disk. One of the ways Apache |
| Kudu achieves this is by supporting column predicates with scanners. Pushing down column predicate |
| filters to Kudu allows for optimized execution by skipping reading column values for filtered out |
| rows and reducing network IO between a client, like the distributed query engine Apache Impala, and |
| Kudu. See the documentation on |
| <a href="https://docs.cloudera.com/runtime/latest/impala-reference/topics/impala-runtime-filtering.html">runtime filtering in Impala</a> |
| for details.</p> |
| |
| <p>CDP Runtime 7.1.5 and CDP Public Cloud added support for Bloom filter column predicate pushdown in |
| Kudu and the associated integration in Impala.</p> |

| <p class="meta">Posted 11 Aug 2020 by Attila Bukor</p> |

| <div class="entry-content"> |
| |
| <p>When Apache Kudu was first released in September 2016, it didn’t support any |
| kind of authorization. Anyone who could access the cluster could do anything |
| they wanted. To remedy this, coarse-grained authorization was added along with |
| authentication in Kudu 1.3.0. This meant allowing only certain users to access |
| Kudu, but those who were allowed access could still do whatever they wanted. The |
| only way to achieve finer-grained access control was to limit access to Apache |
| Impala where access control <a href="/2019/04/22/fine-grained-authorization-with-apache-kudu-and-impala.html">could be enforced</a> by |
| fine-grained policies in Apache Sentry. This method limited how Kudu could be |
| accessed, so we saw a need to implement fine-grained access control in a way |
| that wouldn’t limit access to Impala only.</p> |
| |
| <p>Kudu 1.10.0 integrated with Apache Sentry to enable finer-grained authorization |
| policies. This integration was rather short-lived as it was deprecated in Kudu |
| 1.12.0 and will be completely removed in Kudu 1.13.0.</p> |
| |
| <p>Most recently, since 1.12.0 Kudu supports fine-grained authorization by |
| integrating with Apache Ranger 2.1 and later. In this post, we’ll cover how this |
| works and how to set it up.</p> |
