Class TestFlushSnapshotFromClient

java.lang.Object

org.apache.hadoop.hbase.snapshot.TestFlushSnapshotFromClient

public class TestFlushSnapshotFromClient
extends Object

Test creating/using/deleting snapshots from the client

This is an end-to-end test for the snapshot utility TODO This is essentially a clone of TestSnapshotFromClient. This is worth refactoring this because there will be a few more flavors of snapshots that need to run these tests.
