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.
With an ever-increasing number of IoT use cases on the CDH platform, security for such workloads is of paramount importance. This blog post describes how one can consume data from Kafka in Spark, two critical components for IoT use cases, in a secure manner.
The Cloudera Distribution of Apache Kafka 2.0.0 (based on Apache Kafka 0.9.0) introduced a new Kafka consumer API that allowed consumers to read data from a secure Kafka cluster.

Data security is more important than ever before. At the same time, risk is increasing due to the relentlessly growing number of device endpoints, the continual emergence of new types of threats, and the commercialization of cybercrime. And with Apache Hadoop already instrumental for supporting the growth of data volumes that fuel mission-critical enterprise workloads, the necessity to master available security mechanisms is of vital importance to organizations participating in that paradigm shift.
Cloudera Enterprise 5.8 includes the latest release of Hue (3.10), the web UI that makes Apache Hadoop easier to use.
As part of Cloudera’s continuing investments in user experience and productivity, Cloudera Enterprise 5.8 includes a new release of Hue that makes several common tasks much easier. In the remainder of this post, we’ll provide a summary of the main improvements. (Hue 3.10 is also available for a quick try in one click on demo.gethue.com.)
New SQL Editor
Hue’s new code editor is a single-page app that is much simpler to use than the previous editor.

We are very excited to announce that Apache Sentry has graduated out of Incubator and is now an Apache Top-Level Project! Sentry, which provides centralized fine-grained access control on metadata and data stored in Apache Hadoop clusters, was introduced as an Apache Incubator project back in August 2013. In the past two and a half years,
