To create a namespace in HBase versions 0.96 and greater

1.Open HBase shell from HBase bin using command:

./hbase shell

2.Execute HBase shell command create_namespace 'testa'

hbase(main):006:0> create_namespace 'testa'
Took 0.2373 seconds

Note: namespace is not available in HBase versions < 9.96

As Donald mentioned Namespaces are not a feature of HBase 0.94. They were added in v0.96 (see 0.96 announcement here). (0.95 was a development version not a released version)

namespaces isn't available in 0.94 I believe.

The major effort on namespaces isn't completed yet. See https://issues.apache.org/jira/browse/HBASE-8015

However, it seems like some of it has been committed back. Most of the tickets say that it is fixed against 0.95.2 and 0.98.
