Retrieve a Table implementation for accessing a table. The returned Table is not thread safe, a new instance should be created for each using thread. This is a lightweight operation, pooling or caching of the returned Table is neither required nor desired.

The caller is responsible for calling Table.close() on the returned table instance.

Since 0.98.1 this method no longer checks table existence. An exception will be thrown if the table does not exist only when the first operation is attempted.

指定者:

参数:

tableName - the name of the table

pool - The thread pool to use for batch operations, null to use a default pool.

返回:

a Table to use for interactions with this table

Retrieve a RegionLocator implementation to inspect region information on a table. The returned RegionLocator is not thread-safe, so a new instance should be created for each using thread. This is a lightweight operation. Pooling or caching of the returned RegionLocator is neither required nor desired. RegionLocator needs to be unmanaged

指定者:

getRegionLocator 在接口中 org.apache.hadoop.hbase.client.Connection

Retrieve an Admin implementation to administer an HBase cluster. The returned Admin is not guaranteed to be thread-safe. A new instance should be created for each using thread. This is a lightweight operation. Pooling or caching of the returned Admin is not recommended. Note that HConnection needs to be unmanaged

指定者:

getAdmin 在接口中 org.apache.hadoop.hbase.client.Connection

返回:

an Admin instance for cluster administration

抛出:
