java.lang.Object

org.apache.hadoop.hbase.client.ConnectionImplementation

org.apache.hadoop.hbase.client.ConnectionUtils.MasterlessConnection

All Implemented Interfaces:

Closeable, AutoCloseable, Abortable, ClusterConnection, Connection

Enclosing class:

ConnectionUtils

static class ConnectionUtils.MasterlessConnection
extends ConnectionImplementation

Some tests shut down the master. But table availability is a master RPC which is performed on region re-lookups.
