In HBase, it is possible to create a Table in two ways:

i. HBase Create Table
ii. Creating a Table Using Java API

So, let’s learn both in brief:

i. HBase Create Table
With the help of Create command, we can create a table in HBase. But as a condition, we need to specify the table name and the Column Family name to create one.

Syntax

create ‘<table name>’,’<column family>’

ii. Creating a Table Using Java API
Else we can use createTable() method of HBaseAdmin class for creating a table. To do so, steps are:

Step1: Instantiate HBaseAdmin

Do instantiate the Configuration class. Then also pass this instance to HBaseAdmin, since the class needs the Configuration object as a parameter:

Configuration conf = HBaseConfiguration.create();

HBaseAdmin admin = new HBaseAdmin(conf);

Step2: Create TableDescriptor

Step 3: Execute through Admin

with the help of createTable() method of HBaseAdmin class, it is possible to execute the created table in Admin mode.

admin.createTable(table);
