Examples of HBaseAdmin

org.apache.hadoop.hbase.HBaseAdmin
Provides administrative functions for HBase
org.apache.hadoop.hbase.client.HBaseAdmin
Provides an interface to manage HBase database table metadata + general administrative functions. Use HBaseAdmin to create, drop, list, enable and disable tables. Use it also to add and drop table column families.
See {@link HTable} to add, update, and delete data from an individual table.
Currently HBaseAdmin instances are not expected to be long-lived. For example, an HBaseAdmin instance will not ride over a Master restart.
