| <div class="block">A non-instantiable class that manages creation of <a href="Connection.html" title="interface in org.apache.hadoop.hbase.client"><code>Connection</code></a>s. Managing the lifecycle of |
| the <a href="Connection.html" title="interface in org.apache.hadoop.hbase.client"><code>Connection</code></a>s to the cluster is the responsibility of the caller. From a |
| <a href="Connection.html" title="interface in org.apache.hadoop.hbase.client"><code>Connection</code></a>, <a href="Table.html" title="interface in org.apache.hadoop.hbase.client"><code>Table</code></a> implementations are retrieved with |
| <a href="Connection.html#getTable(org.apache.hadoop.hbase.TableName)"><code>Connection.getTable(org.apache.hadoop.hbase.TableName)</code></a>. Example: |
| |
| <pre> |
| Connection connection = ConnectionFactory.createConnection(config); |
| Table table = connection.getTable(TableName.valueOf("table1")); |
| try { |
| // Use the table as needed, for a single operation and a single thread |
| } finally { |
| table.close(); |
| connection.close(); |
| } |
| </pre> |
| |
| Since 2.2.0, Connection created by ConnectionFactory can contain user-specified kerberos |
| credentials if caller has following two configurations set: |
| <ul> |
| <li>hbase.client.keytab.file, points to a valid keytab on the local filesystem |
| <li>hbase.client.kerberos.principal, gives the Kerberos principal to use |
| </ul> |
| By this way, caller can directly connect to kerberized cluster without caring login and |
| credentials renewal logic in application. |
| |
| <pre> |
| </pre> |
| |
| Similarly, <a href="Connection.html" title="interface in org.apache.hadoop.hbase.client"><code>Connection</code></a> also returns <a href="Admin.html" title="interface in org.apache.hadoop.hbase.client"><code>Admin</code></a> and <a href="RegionLocator.html" title="interface in org.apache.hadoop.hbase.client"><code>RegionLocator</code></a> |
