Chapter 2 mapreduce IntroductionAn ideal part size is usually the size of an HDFS block. The execution node of the map task and the storage node of the input data are the same node, and the hadoop performance is optimal (Data Locality optimization, avoid data transmission over the network ). Mapreduce Process summary: reads a row of data from a file, map function processing, Return key-value pairs; the system sorts the map results. If there are multi

Document directory Minidfscluster Debugging in IDE Regression View Original Background of hadoop's existing testing framework From the first day of using hadoop, we have never left the development of hadoop's own functions or the development of hadoop's own bug fixes. This development model has lasted for several years, but one of the phenomena that can be found is that the bugs we fix or the features we develop have never been very standardize

Opening: Hadoop is a powerful parallel software development framework that allows tasks to be processed in parallel on a distributed cluster to improve execution efficiency. However, it also has some shortcomings, such as coding, debugging Hadoop program is difficult, such shortcomings directly lead to the entry threshold for developers, the development is difficult. As a result, HADOP developers have devel
