ODBC client: The Hive ODBC driver is similar to the JDBC driver in that it uses Thrift to connect to Hive. However, the ODBC driver uses the Hive Server to communicate with it instead of the Hive Server. Hive Services: Hive provides numerous services, including the Hive server2, Beeline,...
Hive is a server side deployable tool that supports structured data and has a JDBC and BI integration. It is a query language like SQL and is used for data analysis and report creation. It is a data warehousing tool that is built on the top of Hadoop Distributed File System (HDFS). It...
