Cloud Hadoop usage scenarios

Available in Classic

The Cloud Hadoop service is applied by creating a Cloud Hadoop cluster in the NAVER Cloud Platform Console. Network and firewall settings and storage settings for accessing cluster nodes are also done from the console. You can then access the UI for each service offered and analyze various data.

To summarize the overall usage scenario of the Cloud Hadoop service, it is as follows.

1. Managing Cloud Hadoop Creation: Console

   • Create a server by selecting a server image and server type
   • User guide page for this step
     • Getting started with Cloud Hadoop

2. ACG Settings: Console

   • Proceed with ACG settings for network access control
   • User guide page for this step
     • Firewall settings (ACG)

3. Using and Managing Cloud Hadoop: console

   • Check cluster information
   • Manage clusters (change the number of nodes, reset admin passwords, back up settings)
   • Manage server connections (change cluster direct access authentication key, change public IP settings, manage authentication keys)
   • View the web UIs that are accessible and their access rules, then click the shortcut links to access them
   • User guide page for this step
     • View and manage Cloud Hadoop information

4. Access to Cluster Nodes and the Web UI: Terminal Program on a PC, Web Browser

   • User guide page for this step
     • Access a Cluster Node with SSH
     • Set UI Access and Password by Services
     • Access the Web UI with Tunneling

5. Using the Web UI: Terminal Program on a PC, Web Browser

   • Use built-in ecosystem Web UI pages by service, such as Ambari, Hue, etc.
   • User guide page for this step
     • Ambari UI
     • Use the Ambari REST API
     • Submit Spark Job with Apache Livy
     • Use Hive
     • Run Hive UDF
     • Connecting CSV Files with Hive External Tables
     • Use Hue
     • Create DB with MySQL Stored Procedure
     • Use OpenTSDB
     • Use Presto
     • Analyze Hive Warehouse Data with Presto
     • Submit Spark Scala Job
     • Use Sqoop
     • Use Zeppelin

6. External linking: PC's terminal program, Web UI, and each service linking

   • Analyze various data by linking DB with Cloud Hadoop applications
   • User guide page for this step
     • Connecting Apache Flume
     • Migrating CDB MySQL Data
     • User guide of Cloud DB for MySQL
     • Connecting Object Storage + Sub Account
     • Data Migration with Object Storage
     • User guide of Object Storage
