When creating Hadoop Cloudera connection profiles, you can select different connection options based on your current system connection setup and your data transfer needs.
Connection Option Description
TDCH Select this option if you plan to use this connection for data transfers between the Cloudera System and a Teradata Database. Teradata Connector for Hadoop (TDCH) enables you to move data between Teradata Databases and Hadoop systems.

Manual metadata update for an Impala instance is required. Please refer to the REFRESH/INVALIDATE METADATA statements in the Cloudera Impala documentation.

JDBC Select this option if you plan to use this connection to access the Cloudera System using SQL from the SQL Editor. This option uses the Impala Hive JDBC Driver to access your Hadoop System. Use the Impala JDBC driver for automatic metadata updates for an Impala instance.
SQL-H Select this option if you plan to use this connection for data transfers from the Cloudera System to an Aster Database.

Manual metadata update for an Impala instance is required. Please refer to the REFRESH/INVALIDATE METADATA statements in the Cloudera Impala documentation.
