Data Access
Cloudera Data Platform Runtime includes Apache Hive 3 and Apache Impala for storing and accessing data in the Hive metastore database. Hive 3 addresses enterprise data warehouse demands for transactional data in the ORC file format. Impala performs high-performance, low-latency SQL queries on data in Parquet and other formats. Hue is a web-based interactive editor for querying the Hive metastore that also creates Oozie workflows. DAS is a web application for performing operations on Hive tables and also provides recommendations for optimizing the performance of your queries.
