Spring, one of the popular application development frameworks for enterprise Java, used by developers to create high performing, easily testable, reusable code without any lock-in, is now at version 3.2 RC1.
Highlights of Spring Framework 3.2 RC1:
• A new Gradle-based framework build has been added, making it easier than ever to contribute to the Spring Framework project on GitHub;
• I
As we've noted before, the open source Hadoop software framework has becom a phenomenon as a way of breaking complicated problems apart, spreading them across many computers, and allowing organiations to glean insight from extremely large data sets.
I am following this tutorial.
http://hadoop.apache.org/docs/mapreduce/current/mapred_tutorial.html
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.
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.

There's a major flaw in the Java-based Spring Framework open-source development code that allows remote-code execution by attackers against applications built with it, according to the security firm which identified the flaw.
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.
Quantcast, an internet audience measurement and ad targeting service, processes over 20 petabytes of data per day using Apache Hadoop and its own custom file system called Quantcast File System (QFS). Today, it’s making that technology available to as open source under an Apache license.
