Feed: R-bloggers. Author: Peter's stats stuff - R. I recently read the high quality book Global Inequality by Branko Milanovic. When reading this sort of thing, I often find I can increase my engagement with a topic by playing around with the data myself. In this day and age, this is much more likely to be possible than a couple of decades back! I remember when I first studied development economics, typing into Lotus 123 the data from tables in the back of a World Development Report. These days to get the same data we just fire up R and ...

Feed: Hadoop – Cloudera Engineering Blog. Author: Justin Kestelyn. Welcome to our fourth edition of “This Month in the Ecosystem,” a digest of highlights from October 2013 (never intended to be comprehensive; for completeness, see Hadoop Weekly). For generating sheer excitement, that month installed a high bar to meet in the future: Hadoop 2 Became Stable with the 2.2 (“GA”) ReleaseThe idea that this news could be done justice in a few sentences strains credulity. (Furthermore, it has been covered elsewhere widely and thoroughly at this point.) Suffice to say here that this release will transform the Big Data ecosystem ... Read More

Feed: Hadoop – Cloudera Engineering Blog. Author: Sandy Ryza. Cloudera Manager lets you add a YARN service in the same way you would add any other Cloudera Manager-managed service. In Apache Hadoop 2, YARN and MapReduce 2 (MR2) are long-needed upgrades for scheduling, resource management, and execution in Hadoop. At their core, the improvements separate cluster resource management capabilities from MapReduce-specific logic. They enable Hadoop to share resources dynamically between MapReduce and other parallel processing frameworks, such as Cloudera Impala; allow more sensible and finer-grained resource configuration for better cluster utilization; and permit Hadoop to scale to accommodate more and ...

Feed: Hadoop – Cloudera Engineering Blog. Author: Aaron Myers. The release of Apache Hadoop 2, as announced today by the Apache Software Foundation, is an exciting one for the entire Hadoop ecosystem. Cloudera engineers have been working hard for many months with the rest of the vast Hadoop community to ensure that Hadoop 2 is the best it can possibly be, for the users of Cloudera’s platform as well as all Hadoop users generally. Hadoop 2 contains many major advances, including (but not limited to): High availability for the HDFS NameNode, which eliminates the previous SPOF in HDFS. Support for ... Read More

Feed: AWS Big Data Blog. When we first looked into the possibility of building a cloud-based data warehouse many years ago, we were struck by the fact that our customers were storing ever-increasing amounts of data, and yet only a small fraction of that data ever made it into a data warehouse or Hadoop system for analysis. We saw that this wasn’t just a cloud-specific anomaly. It was also true in the broader industry, where the growth rate of the enterprise storage market segment greatly surpassed that of the data warehousing market segment.We dubbed this the “dark data” problem. Our ... Read More

Feed: Planet MySQL; Author: MySQL High Availability; In MySQL 8.0.2, users will see the additional columns in the existing Group Replication Performance Schema tables which will provide extended information about Group Replication. Now user can view role and MySQL version of each member of the group, which earlier required a complex set of query. The user can also see additional statistics of each member of the group, like remote applier queue count, remote transactions applied, number of transactions proposed by member and number of proposed transactions rolled back by the group. These have been a constant request from the users of the Group Replication plugin ... Read More

Feed: Hadoop – Cloudera Engineering Blog. Author: Justin Kestelyn. I’ve always held a strong bias that education is most effective when the student learns by doing. As a developer of technical curricula, my goal is to have training participants engage with real and relevant problems as much as possible through hands-on exercises. The high rate at which Apache Hadoop is changing, both as a technology and as an ecosystem, makes developing Cloudera training courses not only demanding but also seriously fun and rewarding. I recently undertook the challenge of upgrading the Cloudera Administrator Training for Apache Hadoop. I more than ... Read More

Feed: Hadoop – Cloudera Engineering Blog. Author: Justin Kestelyn. In December 2012, we described how an internal application built on CDH called Cloudera Support Interface (CSI), which drastically improves Cloudera’s ability to optimally support our customers, is a unique and instructive use case for Apache Hadoop. In this post, we’ll follow up by describing two new differentiating CSI capabilities that have made Cloudera Support yet more responsive for customers: How Cloudera Impala has turbo-charged CSI with support for real-time log file analysis and visualization How Cloudera Search enables interactive data exploration of multiple sources simultaneously from within CSI So, let’s ...
