org.apache.hadoop.hbase.client
Class CoprocessorHConnection

java.lang.Object
  org.apache.hadoop.hbase.client.CoprocessorHConnection

All Implemented Interfaces:: Closeable, Abortable, HConnection

@InterfaceAudience.Private @InterfaceStability.Evolving public class CoprocessorHConnection
extends Object
implements HConnection
extends Object
implements HConnection

Connection to an HTable from within a Coprocessor. We can do some nice tricks since we know we are on a regionserver, for instance skipping the full serialization/deserialization of objects when talking to the server.

You should not use this class from any client - its an internal class meant for use by the coprocessor framework.
