The DataDirect driver for Apache Hive is the only fully-compliant JDBC driver supporting multiple Hadoop distributions out-of-the-box. With the latest release of DataDirect Connect, the JDBC driver also supports the latest iteration of Apache Hive (“Hive2”), which includes improved support for concurrency and authentication. Those enhancements have also become available in key Apache Hadoop distributions such as Cloudera CDH 4.1. DataDirect Connect XE for JDBC 7.1 includes full Hive2 support and Cloudera CDH 4.1 certification. The improved concurrency allows the JDBC driver to manage concurrent connections to the Hive2 server, enabling better scalability and high availability for those applications requiring highly efficient access to Hive databases. In addition, improved authentication to the Hive2 server allows for plain text passwords and better overall authorized access and data security.
