Configure Big Data Tools environment

Install the required plugins

1. Whatever you do in IntelliJ IDEA, you do it in a project. So, open an existing project (File | Open) or create a new project (File | New | Project).

2. Press Ctrl+Alt+S to open the IDE settings and select Plugins | Marketplace.

3. Install the following plugins:

   • Big Data Tools

   • Scala

   Also, check that the Python plugin is enabled. It should be installed by default for IntelliJ IDEA Ultimate.

4. Install the Big Data Tools plugin.

5. Restart the IDE. After the restart, the Big Data Tools tab appears in the rightmost group of the tool windows. Click it to open the Big Data Tools window.

   

Configure a server connection

1. In the Big Data Tools window, click and select the server type. The Big Data Tools Connection dialog opens.

2. In the Big Data Tools Connection dialog, specify the following parameters depending on the server type:

   • File Systems: FS | Local, FS | HDFS

   • Storages: AWS S3, Minio, Linode, Digital Open Spaces, GS, Azure, Yandex Object Storage, Alibaba

   • Monitoring: Spark, Hadoop, Kafka

   • Notebooks: Zeppelin

   • Data Processing Platforms: AWS EMR

   

   Mandatory parameters:

   • Root path: a path to the root directory.

   • Name: the name of the connection to distinguish it between the other connections.

   Optionally, you can set up:

   • Per project: select to enable these connection settings only for the current project. Deselect it if you want this connection to be visible in other projects.

   • Enable connection: deselect if you want to restrict using this connection. By default, the newly created connections are enabled.

   

   Mandatory parameters:

   • Root path: a path to the root directory on the target server.

     When the connection is successfully established the Driver home path field shows the target IP address of connection including a port number. Example: hdfs://127.0.0.1:65224/.

   • Name: the name of the connection to distinguish it between the other connections.

   Optionally, you can set up:

   • Per project: select to enable these connection settings only for the current project. Deselect it if you want this connection to be visible in other projects.

   • Enable connection: deselect if you want to restrict using this connection. By default, the newly created connections are enabled.

   • Enable tunneling (Only NameNode operation). Creates an SSH tunnel to the remote host. It can be useful if the target server is in a private network but an SSH connection to the host in the network is available. SSH tunneling currently works only for operators with the following name nodes: list files, get meta info

     Select the checkbox and specify a configuration of an SSH connection (click ... to create a new SSH configuration).

   Note that the Big Data Tools plugin uses the HADOOP_USER_NAME env variable to login to the server. It this variable is not defined then the user.name property is used.
