TL;DR: In this article, the authors propose a database connecting method capable of simultaneously accessing Hbases of different clusters, which includes the steps that 1, configuration file names of the HBase of the different clusters are obtained from xml configuration files; 2, Configuration examples are established, an addResource method is called to load configuration files of the hBase of different cluster; 3, the established configuration examples are used as initialization parameters, HConnetion reference variables are defined by a HconnectionManager; 4, HTableInterface reference variables correspond to tables in the Hbase of the same clusters
