Spring Hadoop is adding its own functionality into generic concept of resource loading. Resource abstraction in Spring has always been a way to ease resource access in terms of not having a need to know where there resource is and how it’s accessed.
And, Spring for Apache Hadoop is the framework to support application building with Hadoop components like HDFS, MapReduce and Hive etc. Spring provides APIs to work with all these components. Spring also supports integration of Hadoop with other Spring ecosystem projects for real life application development. Consequently, The core of Apache Hadoop consists of a storage part, known as Hadoop Distributed File System (HDFS), and a processing part which is a MapReduce programming model. Hadoop splits files into large blocks and distributes them across nodes in a cluster. It then transfers packaged code into nodes to process the data in parallel. One may also ask, Hadoop Common: The common utilities that support the other Hadoop modules. Hadoop Distributed File System (HDFS™): A distributed file system that provides high-throughput access to application data. Hadoop YARN: A framework for job scheduling and cluster resource management. In respect to this, Hadoop YARN: A framework for job scheduling and cluster resource management. Hadoop MapReduce: A YARN-based system for parallel processing of large data sets. Hadoop Ozone: An object store for Hadoop. Who Uses Hadoop?

Used versions of Hadoop and HBase are officially compatible - fully tested. As handler of HBase native Zookeeper is used. For large clusters is highly recomanded to use external Zookeeper management (not include).
How does the hadoop recordreader work in hadoop?
Hadoop RecordReader uses the data within the boundaries that are being created by the inputsplit and creates Key-value pairs for the mapper. The “start” is the byte position in the file where the RecordReader should start generating key/value pairs and the “end” is where it should stop reading records.
