Examples of org.apache.hadoop.hbase.TableName

org.apache.hadoop.hbase.TableName
Immutable POJO class for representing a table name. Which is of the form: <table namespace>:<table qualifier> Two special namespaces: 1. hbase - system namespace, used to contain hbase internal tables 2. default - tables with no explicit specified namespace will automatically fall into this namespace. ie a) foo:bar, means namespace=foo and qualifier=bar b) bar, means namespace=default and qualifier=bar c) default:bar, means namespace=default and qualifier=bar
