Iceberg Connection Parameters

List of Iceberg connection parameters, descriptions, default values, and supported data types.

The following sections list the required and optional Iceberg connection parameters.
IMPORTANT
  • Currently, Iceberg cannot use MAPRSASL to authenticate to an HPE Ezmeral Data Fabric cluster when the catalog type is hadoop; however, you can use the hive catalog type to connect Iceberg to an HPE Ezmeral Data Fabric cluster.
