The Architecture of Apache Hadoop

Apache Hadoop platform is highly fault-tolerant for system disasters. At the core of Apache Hadoop, there are Hadoop Distributed File System and MapReduce that diffuse high-velocity streams of big data across multiple racks of low-priced servers. Hadoop Distributed File System does not have a limitation on the size of the file for data storage, write, and read operations. The limitation can only arise from the disk capacity of the machine, but not from HDFS. HDFS also...

R has knives out for IBM SPSS and SAS

Introduction ​ Originally Bell Labs has conceived the idea of language S in the mid-1970s to resolve data analytics and statistical conundrums. The purpose of the implementation project was to perform statistical analysis of their corporation leveraging the libraries of Fortran language. The invention of S language did not include the functions needed for statistical computing. In the late 1980s, the act of rebuilding the source code in language C reinvented S languag...
