Virtualization giant VMware has unveiled Spring Hadoop, which integrates its Spring Framework with the Apache Hadoop platform. Spring provides a comprehensive, lightweight framework that will make it easier for devs to build solutions around the Hadoop platform, according to the company. Spring Hadoop is available under the open source Apache 2.0 license and can be downloaded free.
Two major trends in enterprise computing this year show increasing overlap: big data processing and open source cloud adoption.
To Hortonworks, the software company behind open source Apache Hadoop, the connection makes sense.
Where is Dell heading in the big data, business intelligence and analytics software markets? The answer involves Apache Hadoop and Pentaho — an open source software company that seems to be gaining more business momentum. Here’s the update.
First, a little background on each of the players:
Dell has an Emerging Solutions Ecosystem that drives new innovations out to customers.
I am following this tutorial.

javac -classpath ${HADOOP_HOME}/hadoop-core- ${HADOOP_VERSION}.jar:${HADOOP_HOME}/hadoop-mapred-${HADOOP_VERSION}.jar:${HADOOP_HOME}/hadoop-hdfs-${HADOOP_VERSION}.jar -d wordcount_classes
The hadoop version is 0.22.0 and this does not have a hadoop-core-0.22.0.jar though I find hadoop-hdfs-0.22.
Ok, this is the first script I've ever attempted to write so go easy on me. I'm just trying to simple copy a tar.gz file from the directory the script is located to /usr/local/filename.tar.gz The script is run as root so it shouldn't be a permissions issue.
With configuration, installation, and the use of Hadoop in single-node and also the use in multi-node architectures under your belt, you can now turn to the task of developing applications within the Hadoop infrastructure. This article explores the Hadoop APIs and data flow and demonstrates their use with a simple mapper and reducer application.
These days, storing large amounts of data is easy. Where things get complicated is ensuring the integrity and reliability of that data, an increasing challenge as Big Data clusters grow bigger and bigger. This problem has created new opportunities in the Big Data channel, on which companies such as Talend, which has introduced new Hadoop data profiling technology, are working to capitalize.
Wondering what comes after the cloud? Literally, usually sunshine — haha. But metaphorically speaking, the next great frontier may well be big-data. And Hadoop, an open-source project enjoying ever-increasing buzz as of late, will likely be at the fore as that niche evolves. If you don’t know much about Hadoop, it’s time to learn.
Mention big data and the first thing that might come to mind is Hadoop. The open source software framework has recently enjoyed a great deal of popularity among vendors and enterprise users. However, if it is to really be useful to the enterprise, Hadoop may need to be taken out of open source, argues Brian Christian, chief technology officer of Zettaset.
