Feed: Planet big data. Author: Ronald van Loon. I attended the Huawei European Innovation Day recently, and was enthralled by how the new technology is giving rise to industrial revolutions. These revolutions are what will eventually unlock the development potential around the world. It is important to leverage the emerging technologies, since they are the resources which will lead us to innovation and progress. Huawei is innovative in its partnerships and collaboration to define the future, and the event was a huge success. For many people, the concept of Artificial Intelligence (AI) is a thing of the future. It is the technology that has ... Read More

Feed: Cloudera Engineering Blog » Hadoop. Author: Tom White. Apache Hadoop 0.21.0 was released on August 23, 2010. The last major release was 0.20.0 in April last year, so it’s not surprising that there are so many changes in this release, given the amount of activity in the Hadoop development community. In fact, there were over 1300 issues fixed in JIRA (Common, HDFS, MapReduce), the issue tracker used for Apache Hadoop development. Bear in mind that the 0.21.0 release, like all dot zero releases, isn’t suitable for production use. With such a large delta from the last release, it is ... Read More

Feed: Databasejournal.com - Feature Database Articles. Author: . Latches can be confusing. Sessions can wait for them and when those waits become excessive performance degrades. To many they appear to be the same as locks, but they aren't, even though lock waits, when the times get excessive, can also degrade performance. So, what are the differences between latches and locks? Let's examine both and see where they differ, what can cause latch waits and how latch waits can be investigated. Latches are similar to locks but they operate on memory to protect code and internal data structures by preventing concurrent ... Read More

Feed: Cloudera Engineering Blog » Hadoop. Author: Matt Massie. In March of this year, we released our distribution for Apache Hadoop.  Our initial focus was on stability and making Hadoop easy to install. This original distribution, now named CDH1, was based on the most stable version of Apache Hadoop at the time:0.18.3. We packaged up Apache Hadoop, Pig and Hive into RPMs and Debian packages to make managing Hadoop installations easier.  For the first time ever, Hadoop cluster managers were able to bring up a deployment by running one of the following commands depending on your Linux distribution: # yum ...

Feed: Cloudera Engineering Blog » Hadoop. Author: Christophe Bisciglia. There’s been a lot of buzz about Apache Hadoop lately. Just the other day, some of our friends at Yahoo! reclaimed the terasort record from Google using Hadoop, and the folks at Facebook let on that they ingest 15 terabytes a day into their 2.5 petabyte Hadoop-powered data warehouse. But many people still find themselves wondering just how all this works, and what it means to them. We get a lot of common questions while working with customers, speaking at conferences, and teaching new users about Hadoop. If you, or folks ... Read More

Feed: Cloudera Engineering Blog » Hadoop. Author: Christophe Bisciglia. A while back, we noticed a blog post From Arun Jacob over at Evri (if you haven’t seen Evri before, it’s a pretty impressive take on search UI). We were particularly interested in helping Arun and others use EC2 and Hadoop to process data stored on EBS as Amazon makes many public data sets available. After getting started, Arun volunteered to write up his experience, and we’re happy to share it on the Cloudera blog.  -Christophe BackgroundA couple of weeks ago I managed to get a Hadoop cluster up and running on ...

Well, V11.1.2.2 is new, and there are plenty of goodies and enhancements in it. There's a new DSM release. There are new (free) editions of Db2.

Feed: Cloudera Engineering Blog » Hadoop. Author: Christophe Bisciglia. One of the repeating themes we have heard while working with our customers and the community is that Apache Hadoop configuration and deployment is a pain. Often times, Hadoop is the first truly distributed system that administrators encounter, and the problem is made worse by the lack of standardized packages and deployment tools. And some releases are buggy. And upgrades are hard. And the list goes on. In order for Hadoop to truly disrupt the enterprise, it needs to be just as easy to configure, deploy and manage as any other piece ... Read More
