类 HTableWrapper

java.lang.Object

org.apache.hadoop.hbase.client.HTableWrapper

所有已实现的接口:

Closeable, AutoCloseable, HTableInterface, Table

public class HTableWrapper
extends Object
implements HTableInterface

A wrapper for HTable. Can be used to restrict privilege. Currently it just helps to track tables opened by a Coprocessor and facilitate close of them if it is aborted. We also disallow row locking. There is nothing now that will stop a coprocessor from using HTable objects directly instead of this API, but in the future we intend to analyze coprocessor implementations as they are loaded and reject those which attempt to use objects and methods outside the Environment sandbox.
