Big Data tools
The Big Data Tools plugin is available for IntelliJ IDEA 2019.2 and later. It provides specific capabilities to monitor and process data with Zeppelin, AWS S3, Spark, Google Cloud Storage, Minio, Linode, Digital Open Spaces, Microsoft Azure and Hadoop Distributed File System (HDFS).
You can create new or edit existing local or remote Zeppelin notebooks, execute code paragraphs, preview the resulting tables and graphs, and export the results to various formats.
The plugin supports many IDE features to work with notebooks:
Coding assistance for Scala
Inspection and quick-fixes, including fixes for notebook dependencies.
Browsing, creating, and deleting notebooks
Adding and deleting paragraphs
Running SQL statements

If you have any questions regarding the Big Data Tools plugin, click the Support link and select one of the available options. You can join the support Slack channel, submit a ticket in the YouTrack system, or copy the support email to send your question.
In the notebook editor, you can add and execute Python, Scala and SQL code paragraphs. When editing your code paragraph, you can use all the coding assistance features available for a particular language. Code warnings and errors will be highlighted in the corresponding code constructs in the scrollbar. The results of paragraph execution are shown in the preview area below each paragraph.
Use the notebook editor toolbar for the basic operations with notebooks:
|Executes all paragraphs in the notebook.|
