Before you begin

Before using the Catalog Input step, be aware of the following conditions:

• You must have an established Catalog connection to Data Catalog. For details, see Access to Pentaho Data Catalog.
• S3 must be configured as the Default S3 Connection in VFS Connections to access S3 storage. For details, see Connecting to Virtual File Systems.
• You must have an established PDI connection to the cluster(s) you plan on using. For example, a Hadoop driver must be configured as a named connection for your distribution for accessing HDFS. For information on named connections, see Connecting to a Hadoop cluster with the PDI client.
