Java – JUnit external resource @ rule order

I want to use multiple external resources in my test class, but I have a problem sorting external resources

This is a code snippet:

public class TestPigExternalResource {

     // hadoop external resource,this should start first
     @Rule
     public HadoopSingleNodeCluster cluster = new HadoopSingleNodeCluster();

     // pig external resourcem,this should wait until hadoop external resource starts
     @Rule
     public  PigExternalResource pigExternalResource = new PigExternalResource(); 

     ...  
}

The problem is that it tries to start the pig before Hadoop starts, so I can't connect to the local Hadoop single node cluster

Is there any way to order JUnit rules?

thank you

Solution

You can use rulechain

@Rule
public TestRule chain= RuleChain.outerRule(new HadoopSingleNodeCluster())
                           .around(new PigExternalResource());
