Manage the HDFS Connector
Composer offers connection to Cloudera’s open source Hadoop platform - Cloudera Distributed Hadoop (CDH)*. CDH provides unified batch processing, interactive SQL, interactive search, and role-based access controls. In addition, it offers enterprise-grade continuous availability. Specifically, Composer connects to CDH’s fault‐tolerant storage system called the Hadoop Distributed File System (HDFS).
The Composer HDFS connector uses its own embedded Apache Spark functionality. It supports Apache Spark 2.2 in its implementation.
By default, the HDFS connector is not included with Composer. You or your administrator need to download and enable it before configuring the connector.
After the connector has been set up, you can create data source configurations that specify the necessary connection information and identify the data you want to use. See Manage Data Source Configurations for more information. After data sources are configured, they can be used to create dashboards and visuals from your data. See Create Dashboards.
