Thanks to Cody Koeninger, Senior Software Engineer at Kixer, for the guest post below about Apache Kafka integration points in Apache Spark 1.3. Spark 1.3 will ship in CDH 5.4.
The new release of Apache Spark, 1.3, includes new experimental RDD and DStream implementations for reading data from Apache Kafka. As the primary author of those features, I’d like to explain their implementation and usage. You may be interested if you would benefit from:
- More uniform usage of Spark cluster resources when consuming from Kafka
- Control of message delivery semantics
- Delivery guarantees without reliance on a write-ahead log in HDFS
- Access to message metadata
I’ll assume you’re familiar with the Spark Streaming docs and Kafka docs.
Strata + Hadoop World San Jose 2015 (Feb. 17-20) is a focal point for learning about production-izing Hadoop.
Strata + Hadoop World sessions have always been indispensable for learning about Hadoop internals, use cases, and admin best practices. When deep learning is needed, however—and deep dives are a necessity if you’re running Hadoop in production, or aspire to—tutorials are your ticket.
This year, tutorials span a range of topics that are central in today’s Hadoop conversation,
The community effort to make Apache Spark an execution engine for Apache Hive is making solid progress.
Apache Spark is quickly becoming the programmatic successor to MapReduce for data processing on Apache Hadoop. Over the course of its short history, it has become one of the most popular projects in the Hadoop ecosystem, and is now supported by multiple industry vendors—ensuring its status as an emerging standard.
Two months ago Cloudera,
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 combination of OpenShift and Kite SDK turns out to be an effective one for developing and testing Apache Hadoop applications.
At Cloudera, our engineers develop a variety of applications on top of Hadoop to solve our own data needs (here and here). More recently, we’ve started to look at streamlining our development process by using a PaaS (Platform-as-a-Service) for some of these applications. Having single-click deployment and updates to consistent development environments lets us onboard new developers more quickly,
