function of hive, it can do more complicated SQL query operation.Impala provides an interactive SQL for direct querying of data stored in HDFs, HBase. In addition to using the same unified storage platform as Hive, Impala also uses the same metadata, SQL syntax (Hive SQL), ODBC Driver and user interface (Hue beeswax).

I've described two ways in which hive imports analysis results into MySQL tables, respectively: Sqoop import and Using hive, MySQL JDBC driver, now I'm going to introduce a third, and use a lot more ways--using hive custom Functions ( UDF or genericudf) inserts each record into a database table.First, using the UDF methodUsing UDF is a simple implementation, as

Label:Cause of the problem:When an application accesses a database, such as ASP, ASP. NET, VB, LoadRunner, and so on, if the data source is configured in a 64-bit ODBC-driven Configuration Manager, an ODBC-driven scenario may not be found.This is because these applications are 32-bit applications that do not have access to the data sources configured in the 64-bit ODBC
