‘Hadoop 2.0 Makes Big Data Even More Accessible’ – ‘ReadWrite’
The latest post on ‘ReadWrite’ is titled “Hadoop 2.0 Makes Big Data Even More Accessible”.
Brian Proffitt says, “It took a little longer than expected, but the Apache Software Foundation has announced the general availability of Apache Hadoop 2.0 yesterday, which will ultimately be an elephant-sized step in how Hadoop is used for managing big data collections.
The biggest change to Apache Hadoop 2.2.0, the first generally available version of the 2._x_ series, is the update to the MapReduce framework to Apache YARN, also known as MapReduce 2.0. MapReduce is a big feature in Hadoop—the batch processor that lines up search jobs that go into the Hadoop distributed file system (HDFS) to pull out useful information. In the previous version of MapReduce, jobs could only be done one at a time, in batches, because that’s how the Java-based MapReduce tool worked”.
