Following these best practices can make your upgrade path to CDH 5 relatively free of obstacles.
Upgrading the software that powers mission-critical workloads can be challenging in any circumstance. In the case of CDH, however, Cloudera Manager makes upgrades easy, and the built-in Upgrade Wizard, available with Cloudera Manager 5, further simplifies the upgrade process. The wizard performs service-specific upgrade steps that, previously, you had to run manually, and also features a rolling restart capability that reduces downtime for minor and maintenance version upgrades.
With Cloudera Director, cloud deployments of Apache Hadoop are now as enterprise-ready as on-premise ones. Here’s the technology behind it.
As part of the recent Cloudera Enterprise 5.2 release, we unveiled Cloudera Director, a new product that delivers enterprise-class, self-service interaction with Hadoop clusters in cloud environments. (Cloudera Director is free to download and use, but commercial support requires a Cloudera Enterprise subscription.) It provides a centralized administrative view for cloud deployments and lets end users provision and scale clusters themselves using automated,
The Transaction Processing Council (TPC), working with Cloudera, recently announced the new TPCx-HS benchmark, a good first step toward providing a Big Data benchmark.
In this interview by Roberto Zicari with Francois Raab, the original author of the TPC-C Benchmark, and Yanpei Chen, a Performance Engineer at Cloudera, the interviewees share their thoughts on the next step for benchmarks that reflect real-world use cases.

Unique across all options, Cloudera Manager makes it easy to do what would otherwise be a disruptive operation for operators and users.
For the increasing number of customers that rely on enterprise data hubs (EDHs) for business-critical applications, it is imperative to minimize or eliminate downtime — thus, Cloudera has focused intently on making software upgrades a routine, non-disruptive operation for EDH administrators and users.
With Cloudera Manager 4.6 and later,
Oozie’s new HA qualities help cluster operators sleep well at night. Here’s how it works.
One of the big new features in CDH 5 for Apache Oozie is High Availability (HA). In designing this feature, the Oozie team at Cloudera had two main goals: 1) Don’t change the API or usage patterns, and 2) the user shouldn’t even have to know that HA is enabled. In other words, we wanted Oozie HA to be as easy and transparent as possible.
