Apache Phoenix enables you to interact with HBase using SQL. In HDP 2.5, we have introduced support for ODBC drivers. With this, you can connect any ODBC applications to HBase via Apache Phoenix. This enables you to use familiar business intelligence tools to run analysis on big datasets. This tutorial is designed to
