Feed: Cloudera Engineering Blog » Hadoop. Author: Aaron Kimball. Cloudera customers usually have two major sources of data: log files, which can be imported to Hadoop via Flume, and relational databases. Throughout the previous releases of CDH2 and CDH3, Cloudera has included a package we’ve developed called Sqoop. Sqoop can perform batch imports and exports between relational databases and Hadoop, storing data in HDFS and creating Hive tables to hold results. We described its motivation and some use cases in a previous blog post a while ago. In CDH3b2, we’ve included a greatly-expanded version of Sqoop which has had a ... Read More

Feed: Cloudera Engineering Blog » Hadoop. Author: Chad Metcalf. One of the more common requests we receive from the community is to package Apache HBase with Cloudera’s Distribution for Apache Hadoop. Lately, I’ve been doing a lot of work on making Cloudera’s packages easy to use, and recently, the HBase team has pitched in to help us deliver compatible HBase packages. We’re pretty excited about this, and we’re looking forward to your feedback. A big thanks to Andrew Purtell, a Senior Architect at TrendMicro and HBase Contributor, for leading this packaging project and providing this guest blog post. -Chad Metcalf ... Read More

Feed: Cloudera Engineering Blog » Hadoop. Author: Amr Awadallah. (guest blog post by Pete Skomoroch) In a previous post, I outlined how to build a basic trend tracking site called trendingtopics.org with Cloudera’s Distribution for Hadoop and Hive.  TrendingTopics uses Hadoop to identify the top articles trending on Wikipedia and displays related news stories and charts.  The data powering the site was pulled from an Amazon EBS Wikipedia Public Dataset containing 8 months of hourly pageview logfiles.  In addition to the pageview logs, the EBS data volume also includes the full text content and link graph for all articles.  This ...

Feed: Alation. Author: Aaron Kalb. Tools like MicroStrategy and Tableau make it easy for business users to quickly turn raw data into visualizations and reports. But before you can even start, you have to find a relevant data set, understand it, and trust it. Then you have to connect to it, which can involve many steps and typing many slashes and dots (mysql://10.1.abc/xyz, etc.).Even if you have Alation Catalog to facilitate finding, understanding, and trusting data assets, the process of actually connecting to data can be intimidating, difficult, and error-prone. It introduces needless friction in what should be a smooth ... 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: Amr Awadallah. At Cloudera, we frequently work with leading Hadoop developers to produce guest blog posts of general interest to the community. We started a project with Pete Skomoroch a while back, and we were so impressed with his work, we’ve decided to bring Pete on as a regular guest blogger. Pete can show you how to do some pretty amazing things with Hadoop, Pig and Hive and has a particular bias towards Amazon EC2. With that, I’m happy to welcome Pete to the blog, and hope you enjoy his first post as much ... Read More

Feed: Cloudera Engineering Blog » Hadoop. Author: Christophe Bisciglia. On June 10th, more than 750 people from around the world descended on the Santa Clara Marriott to share their love for a little stuffed elephant named Hadoop. It was a good week to be part of this exploding community, and I want to extend Cloudera’s heartfelt thanks to everyone who made it possible, especially our friends at Yahoo! who organized this Summit. Most importantly, I want to thank all of you who were able to participate. I know many of you couldn’t make it to California this time, so I ... Read More

Debian logo by Software in the Public Interest, Inc. (CC-BY-SA) MySQL and Debian 9 “Stretch” Debian 9 (“Stretch”) was released on June 17, and we congratulate the Debian community on another iteration of a central Linux distro.

Feed: IBM Big Data & Analytics Hub - All Content. Author: chris-gillar. If you read a lot of development blogs nowadays, you’ll probably notice a common theme: developers don’t want to deal with databases. They want to focus on designing, building, testing, and deploying applications that deliver value to the business as quickly as possible.Because of this, developers often instinctively reach for whichever database platform minimizes the amount of time needed to design a schema, and allows them to get started fast. Focusing on the speed of development and the ability to “fail fast” is commendable, but this approach doesn’t ... Read More
