In this article, we will study Hadoop Architecture. The article explains the Hadoop architecture and the components of Hadoop architecture that are HDFS, MapReduce, and YARN. Before 2.0, the MapReduce API resided in the org.apache.accumulo.core.client package of the accumulo-core jar. While this old API still exists and can be used, it has been deprecated and will be removed eventually. Configure dependencies for your MapReduce job Before 2.0, Accumulo used the same versions for dependencies (such as Guava) as Hadoop.

The first is the map job, which takes a set of data and converts it into another set of data, where individual elements are broken down into tuples (key/value pairs). Hadoop MapReduce provides facilities for the application-writer to specify compression for both intermediate map-outputs and the job-outputs i.e.

output of the reduces. It also comes bundled with CompressionCodec implementation for the zlib compression algorithm.
