create
Definition
Creates a new table. Requires a table name and at least one column family specification. Optionally, you can define table-scope and configuration parameters. Each column specification can be a simple string containing a column family name, or a dictionary using a key/value syntax with curly-braces. In the second case specifying the NAME attribute is mandatory.
Usage
create '[<namespace_name>:]<table_name>',
'<column_family>' | {NAME => '<column_family>'[,
<cf_attribute_name> => <cf_attribute_value>,...]
}[,...][,
{<table_attribute_name> => <table_attribute_value>,[...]}][,

Examples
Creating a table in the default namespace without dictionaries
hbase(main):005:0> create 't1', 'cf1', 'cf2' Created table t1 Took 1.2482 seconds => Hbase::Table - t1
Using a new namespace and dictionaries for column families defining
hbase(main):001:0> create 'ns1:t2', {NAME => 'cf1', TTL => 2592000}, {NAME => 'cf2', VERSIONS => 5}
Created table ns1:t2
Took 1.6133 seconds
=> Hbase::Table - ns1:t2
