Namespace in HBase?

Question

How can I list down all the tables created under a single namespace in HBase? In Hbase, is there anything like show tables; which we can use in Hive to find all tables under a particular database.

Answer 1

You can use commands list_namespace_tables from HBase shell. It lists all tables that are members of the namespace. Example

hbaseshell> list_namespace_tables 'default'

You can list the namespaces like so:

hbaseshell> list_namespace
NAMESPACE
default
hbase
