Class TestTimestampsFilter

java.lang.Object

org.apache.hadoop.hbase.client.TestTimestampsFilter

public class TestTimestampsFilter
extends Object

Run tests related to TimestampsFilter using HBase client APIs. Sets up the HBase mini cluster once at start. Each creates a table named for the method and does its stuff against that.
