[0118] Example: Combined with floating car data, an application example of clustering travel density points is used to further illustrate this method.
[0119] refer to Figure 5 , the main steps of this method are:
[0120] Step 1, virtualization environment
[0121] In one blade server, 8 virtual machines are virtualized, and the virtual machines are allocated on different hard disks, and IPs are assigned to establish mutual communication. The system is Centos6.5, 4 64-bit CPUs, and 8G memory.
[0122] Step 2: Build the Hadoop platform
[0123] Install Hadoop-2.2.0 in each virtual machine, configure the configuration file in the / etc / hadoop directory for each node in the cluster, and set the attribute parameters dfs.namenode and dfs.datanode in the file to make the cluster contain Two master nodes master (one active node, one hot standby node) and multiple data nodes datanode; through the setting of attribute parameters mapred.jobtracker and mapred.tasktrack...
