DataNucleus is a middleware that implements the jpa interface, makes it easy to connect to Hbase, and maps entity classes in model (@ Entity,@Id... ), encapsulated by dataNucleus. Just like Hibernate, encapsulate the sql statement.

When you use Datanuclues in myeclipse/eclipse, you need to install a plug-in for datanucleus by:

Plug-in download address: http://www.datanucleus.org/downloads/eclipse-update/ (download automatically using myeclipse/eclipse)

Myeclipse add plug-in

Eclipse add plug-in

If there is no response in myeclipse, manually place the plug-in's jar package in myeclipse's dropins file (which also holds hadoop's plug-in) and restart myeclipse.

Install the DataNucleus plug-in in eclipse, and the next step will allow you to restart, as follows

After starting eclipse/myeclipse again, right-click on the project to see the options for DataNucleus, as shown in the figure
