Hive index, hive 1. Hive index Overview Hive indexes aim to improve the query speed of specified columns in Hive tables. If no index exists, a query similar to 'where tab1.col1 = 10', Hive loads the entire table or partition and

The purpose of configuring hive and HBase integration is to use the HQL syntax to implement additions and deletions of hbase database, the basic principle is to use the API interface between them to communicate with each other, the communication is mainly dependent on the Hive_hbase-handler.jar tool class. Note, however, that using hive to manipulate tables in HBase simply provides convenience, as described

The integration of hive and hbase is to use their own external API interface to communicate with each other, communication is mainly dependent on hive-hbase-handler.jar tools; hive-hbase-handler.jar in the hive lib package instead of in hbase Lib, hive0.6 version later; Create an hbase table when creating a

The premise of integrating hive is that the Apache Hadoop cluster can start normally.Hadoop version apach2.6.0 hive version: 1.2.11. Install MySQL and give permissions:1.1: Create hive user and password:Create user ' hive ' identified by ' 123456 '1.2: Create the database: creates the databases

Opening Remarks: Hive and HBase integration function is to use their own external API interface communication, mutual communication is mainly rely on hive_hbase-handler.jar tool class (HiveStorageHandlers: there is still some interest in hive_hbase-handler.jar this stuff, free to grind.

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
