Class TestSplitTransactionOnCluster

java.lang.Object

org.apache.hadoop.hbase.regionserver.TestSplitTransactionOnCluster

public class TestSplitTransactionOnCluster
extends Object

Like TestSplitTransaction in that we're testing SplitTransactionImpl only the below tests are against a running cluster where TestSplitTransaction is tests against a bare HRegion.
