Class HBaseHbck

java.lang.Object

org.apache.hadoop.hbase.client.HBaseHbck

All Implemented Interfaces:

Closeable, AutoCloseable, Abortable, Hbck

@InterfaceAudience.Private
public class HBaseHbck
extends Object
implements Hbck

Use ClusterConnection.getHbck() to obtain an instance of Hbck instead of constructing an HBaseHbck directly. This will be mostly used by hbck tool.

Connection should be an unmanaged connection obtained via ConnectionFactory.createConnection(Configuration).

An instance of this class is lightweight and not-thread safe. A new instance should be created by each thread. Pooling or caching of the instance is not recommended.
