Download Type 4 JDBC drivers associated with the JCBC-compliant databases that you want to access.
To optimize the Sqoop mapping performance on the Spark engine while writing data to an HDFS complex file target of the Parquet format, download the following .jar files:
Changes take effect after you recycle the Data Integration Service. At run time, the Data Integration Service copies the .jar files to the Hadoop distribution cache so that the .jar files are accessible to all nodes in the cluster.
