It briefly introduces the Hadoop version development history and its evolution process, elaborates the Hadoop 1.0 HDFS design idea, architecture, read/write data process and graphs architecture, task execution process, and Hadoop 1.0 function shortage problems. In view of the shortage of Hadoop 1.0 function, it introduces the Hadoop 2.0 enhancements solutions, including Na-meNode HA solutions, HDFS Federation scheme and YARN design principle, etc.
