The authors observed that Apache Spark recently sent some unusual events, Databricks will provide $14m USD support Spark,cloudera decided to support Spark,spark is considered a big issue in the field of large data. A good first impression the author believes that he has been dealing with Scala's API (spark using Scala) for some time, and, to tell you the truth, was very impressive at first because spark was so small and good. The basic abstraction is the projectile ...

Projects in the private cloud using CDH (Cloudera Distribution Including Apache Hadoop) Hadoop cluster for big data computing. As a big fan of Microsoft, deploying CDH into Windows Azure VMs is my inevitable choice. Because there are multiple open source services in the CDH, there are many ports that virtual machines need to open. Windows Azure virtual machine's network is securely isolated, so in Windows Azu ...

So far, it's time to stop hype about the lack of big data talent and start training and recruiting programs. Experts are trained and not born. One question you need to answer is whether you need technical expertise or data expertise. Expertise allows SQL databases or Hadoop clusters to be used. Data expertise allows us to leverage data mining, text mining, forecasting and machine learning techniques. Either way, we should first of all assume that cultivating talent from existing staff is the most important ...

Big data is still considered a bubble gold? The close attention of businesses, the media, and even the general public is only superficial. The most persuasive data comes from the valuation of Hadoop startups related to big data.

Before yarn, Hadoop was only available for offline processing scenarios. Based on real-time demand, organizations have developed their own streaming framework, this time we are talking about two sql-on-hadoop projects, as well as two well-known Hadoop solution Providers--impala vs. Stinger.

Preface Having been in contact with Hadoop for two years, I encountered a lot of problems during that time, including both classic NameNode and JobTracker memory overflow problems, as well as HDFS small file storage issues, both task scheduling and MapReduce performance issues. Some problems are Hadoop's own shortcomings (short board), while others are not used properly. In the process of solving the problem, sometimes need to turn the source code, and sometimes to colleagues, friends, encounter ...

In the work life, some problems are very simple, but often search for half a day can not find the required answers, in the learning and use of Hadoop is the same.  Here are some common problems with the Hadoop cluster settings: 3 models that 1.Hadoop clusters can run?  Single-machine (local) mode pseudo-distributed mode 2. Attention points in stand-alone (local) mode? There is no daemon in stand-alone mode (standalone), ...
