public class TablePool
extends Object

Table Pool singleton to get the DomainList, RecipientRewriteTable and UserRepository HBase tables. TODO Two getInstance methods are public, one for the impl, one for the tests. This is not good.

Method Detail

getInstance

public static TablePool getInstance()
                             throws IOException

Use getInstance to get an instance of the HTablePool. Don't give any configuration, the default one will be used via HBaseConfiguration.create(Configuration). If you want to create the instance with a specific HBaseConfiguration, use getInstance(Configuration)

Returns:

An instance using a default configuration

Throws:

IOException

getInstance

public static TablePool getInstance(org.apache.hadoop.conf.Configuration configuration)
                             throws IOException

Use getInstance to get an instance of the HTablePool. You can give at first call a specific HBaseConfiguration to suit your needs.

Parameters:

configuration -

Returns:

An instance of HTablePool

Throws:

IOException

getDomainlistTable

public org.apache.hadoop.hbase.client.HTable getDomainlistTable()

Get an instance of the HDomainList table.

Returns:

An instance of HDomainList

getRecipientRewriteTable

public org.apache.hadoop.hbase.client.HTable getRecipientRewriteTable()

Get an instance of the RecipientRewriteTable table.

Returns:

An instance of RecipientRewriteTable

getUsersRepositoryTable

public org.apache.hadoop.hbase.client.HTable getUsersRepositoryTable()

Get an instance of the UsersRepository table.

Returns:

An instance of UsersRepository

putTable

public void putTable(org.apache.hadoop.hbase.client.HTable table)

Put back the table in the pool after usage. With later HBase versions, we won't have to put back the table in the pool. See https://issues.apache.org/jira/browse/HBASE-4054

Parameters:

table -
