This new release includes, among other things, support for “slicing and dicing” workloads by user/application/report, workload breakdown by similar queries, and alerts for Apache Hive and Apache Impala (incubating) best practices.
Cloudera Navigator Optimizer enables database architects and database administrators (DBAs) to gain in-depth understanding of their SQL workloads running in data warehouse environments or on Apache Hadoop. Navigator Optimizer makes planning offload projects more predictable by assessing risk and reducing development costs.
This new release contains, among other things, support for usage-based billing, deployments to Microsoft Azure, and deployments across providers or regions.

Learn how analyzing stats from professional sports leagues is an instructive use case for data analytics using Apache Spark with SQL. Covered in this installment: data exploration with Apache Impala (incubating) and Hue.
In Part 1 of this series, I introduced the topic of using fantasy sports analytics as an instructive use case for exploring the Apache Hadoop ecosystem. In that installment, we focused on data processing by taking a collection of data from Basketball-Reference.com and enriching it with z-scores and normalized z-scores to analyze the relative value of NBA players.
In this installment, we provide insight into how the Fair Scheduler works, and why it works the way it does.
In Part 3 of this series, you got a quick introduction to Fair Scheduler, one of the scheduler choices in Apache Hadoop YARN (and the one recommended by Cloudera). In Part 4, we will cover most of the queue properties, some examples of their use, as well as their limitations.
Using Apache Impala (incubating) on top of Apache Kudu (incubating) has significant performance benefits
Apache Kudu (incubating) is the newest addition to the set of storage engines that integrate with the Apache Hadoop ecosystem. The promise of Kudu is to deliver high-scan performance, targeting analytical workloads, while allowing users to concurrently insert, update, and delete records. With these properties, Kudu becomes a viable alternative to existing combinations of HDFS and/or Apache HBase to achieve similar results with less complicated ETL pipelines,
