Big Data Management uses third-party Hadoop utilities such as Sqoop to process data efficiently.
Sqoop is a Hadoop command line program to process data between relational databases and HDFS through MapReduce programs. You can use Sqoop to import and export data. When you use Sqoop, you do not need to install the relational database client and software on any node in the Hadoop cluster.
To use Sqoop, you must configure Sqoop properties in a JDBC connection and run the mapping in the Hadoop environment. You can configure Sqoop connectivity for relational data objects, customized data objects, and logical data objects that are based on a JDBC-compliant database. For example, you can configure Sqoop connectivity for the following databases:
IBM DB2 for z/OS
Microsoft SQL Server
The Model Repository Service uses JDBC to import metadata. The Data Integration Service runs the mapping in the Hadoop run-time environment and pushes the job processing to Sqoop. Sqoop then creates map-reduce jobs in the Hadoop cluster, which perform the import and export job in parallel.
Specialized Sqoop Connectors
When you run mappings through Sqoop, you can use the following specialized connectors:
You can use OraOop with Sqoop to optimize performance when you read data from Oracle. OraOop is a specialized Sqoop plug-in for Oracle that uses native protocols to connect to the Oracle database.
You can configure OraOop when you run Sqoop mappings on the Hive engine.
Teradata Connector for Hadoop (TDCH) Specialized Connectors for Sqoop
You can use the following TDCH specialized connectors for Sqoop when you read data from or write data to Teradata:
Cloudera Connector Powered by Teradata
Hortonworks Connector for Teradata (powered by the Teradata Connector for Hadoop)
Cloudera Connector Powered by Teradata and Hortonworks Connector for Teradata are specialized Sqoop plug-ins that Cloudera and Hortonworks provide for Teradata. These TDCH Sqoop Connectors use native protocols to connect to the Teradata database.
You can configure the Cloudera Connector Powered by Teradata and Hortonworks Connector for Teradata when you run Sqoop mappings on the Blaze engine.
