supports submission via local KUBECTL proxy. You can use an authentication agent to communicate directly with an API server without having to pass credentials to Spark-submit. The local agent can start by running the following command: If our local agent is listening on port 8001, we will submit the code shown below: Communication between the Spark and kubernetes clusters is performed using the Fabric8

Restart idea: Restart idea: After restart, enter the following interface: Step 4: Compile scala code in idea: First, select "create new project" on the interface that we entered in the previous step ": Select the "Scala" option in the list on the left: To facilitate future development, select the "SBT" option on the right: Click "Next" to go to the next step and set the name and directory of the scala project: Click "finish" to create the project: Because we have selec

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 name of the machine in the configuration file is

. From the configuration above, we can see that we use the master node as the master node and as the data processing node. This is due to the consideration of three copies of our data and the limited number of machines. Copy the master configured masters and slaves files to the conf folder under the hadoop installation directory of slave1 and slave2 respectively: Go to the slave1 or slave2 node to check the content of the masters and slaves files: It is found that the copy is completel

slave2 machines. In this case, the id_rsa.pub of slave1 is sent to the master, as shown below: At the same time, the slave2 id_rsa.pub is sent to the master, as shown below: Check whether the data has been copied on the master: Now we can see that the public keys of slave1 and slave2 nodes have been transmitted. All public keys are integrated on the master node: Copy the master's public key information authorized_keys to the. SSH directory of slave1 and slave1: Log on to slave1

The command to end historyserver is as follows: Step 4: Verify the hadoop distributed Cluster First, create two directories on the HDFS file system. The creation process is as follows: /Data/wordcount in HDFS is used to store the data files of the wordcount example provided by hadoop. The program running result is output to the/output/wordcount directory, through web control, we can find that we have successfully created two folders: Next, upload the data of the local file to the HDFS

Save and run the source command to make the configuration file take effect. Step 3: Run idea and install and configure the idea Scala development plug-in: The official document states: Go to the idea bin directory: Run "idea. Sh" and the following page appears: Select "Configure" To Go To The idea configuration page: Select plugins To Go To The plug-in installation page: Click the "Install jetbrains plugin" option in the lower left corner to go to the following page: Enter "Scala"
