Let's take a look at hadoop the definitive guid tonight. In chapter 3, we will talk about HDFS. I will follow his example to get it done in eclipse.Code, The execution has always reported an error, said not to connect localhost: 8020, I checked the configuration file, it does not have the configuration of this port, but the core-site.xml has a HDFS: localhost: 9000, I think Port 8020 will be enabled by defa

Tonight look at the Hadoop the definitive GUID, to the third chapter about HDFs, I follow his example, in Eclipse get good code, execution has been error, said not even localhost:8020, I checked the next configuration file, There is really no configuration of this port, but core-site.xml inside there is a hdfs:localhost:9000, see there is no way to try the idea, that will default to start 8020 port, is not

MapReduce implements matrix multiplication-implementation code Previously I wrote an article on how MapReduce implements the Matrix Multiplication Algorithm: Mapreduce implements the algorithm idea of matrix multiplication. To give you a more intuitive understanding of program execution, we have compiled the implementation code for your reference.
