Start and view the cluster status Step 1: Start the hadoop cluster, which is explained in detail in the second lecture. I will not go into details here: After the JPS command is run on the master machine, the following process information is displayed: When JPS is used on slave1 and slave2, the following process information is displayed:

in/etc/hosts on slave2. The configuration is as follows: Save and exit. In this case, we can ping both master and slave1; Finally, configure the ing between the host name and IP address in/etc/hosts on the master. The configuration is as follows: At this time, the ping command is used on the master to communicate with the slave1 and slave2 machines: It is found that the machines on the two slave nodes have been pinged. Finally, let's test the communication between the

Step 1: Test spark through spark Shell Step 1:Start the spark cluster. This is very detailed in the third part. After the spark cluster is started, webui is as follows: Step 2: Start spark shell: In this case, you can view the shell in the following Web console:

First, modify the core-site.xml file of the Master, where the content of the file is: We changed the "localhost" domain name to "master ": In the same operation, open the slave1 and slave2 node core-site.xml and change the "localhost" domain name to "master ". Second, modify the master, slave1, slave2 mapred-site.xml file. Go to the mapred-site.xml file of the master node, change the localhost domain name to master, save and exit. Similarly, open the slave1 and slave2 node mapred-site.x

Step 1: software required by the spark cluster; Build a spark cluster on the basis of the hadoop cluster built from scratch in Articles 1 and 2. We will use the spark 1.0.0 version released in May 30, 2014, that is, the latest version of spark, to build a spark Cluster Based

follows: Step 1: Modify the host name in/etc/hostname and configure the ing between the host name and IP address in/etc/hosts: We use the master machine as the master node of hadoop. First, let's take a look at the IP address of the master machine: The IP address of the current host is "192.168.184.20 ". Modify the host name in/etc/hostname: Enter the configuration file: We can see the default name when installing ubuntu. The nam
