An SQL Editor for Apache Spark SQL with Livy
December 2020 Update: Spark SQL queries with the SparkSql Thrift Server instead of Livy
Spark SQL is convenient for embedding clean data querying logic within your Spark apps. Hue brings an Editor so that it is easier to develop your SQL snippets.
As detailed in the documentation, Spark SQL comes with different connectors. Here we will just show with Livy.
Apache Livy provides a bridge to a running Spark interpreter so that SQL, pyspark and scala snippets can be executed interactively. Livy as originally created within the Hue project in order to offer a REST API for easily interacting with Spark.
In the hue.ini configure the API url:
# The Livy Server URL.
And as always, make sure you have an interpreter configured:
And that’s it, the editor will appear:
Here are some of the future improvements:
- Database/table/column autocomplete is currently empty
- SQL grammar autocomplete can be extended
- SQL Scratchpad module to allow a mini SQL Editor popup is in progress
