                           throws java.lang.Exception

Throws:

java.lang.Exception

testBalanceCluster

public void testBalanceCluster()
                        throws java.lang.Exception

Test the load balancing algorithm. Invariant is that all servers of the group should be hosting either floor(average) or ceiling(average)

Throws:

java.lang.Exception

testBulkAssignment

public void testBulkAssignment()
                        throws java.lang.Exception

Tests the bulk assignment used during cluster startup. Round-robin. Should yield a balanced cluster so same invariant as the load balancer holds, all servers holding either floor(avg) or ceiling(avg).

Throws:

java.lang.Exception

testGetMisplacedRegions

public void testGetMisplacedRegions()
                             throws java.lang.Exception

Throws:

testRetainAssignment

public void testRetainAssignment()
                          throws java.lang.Exception

Test the cluster startup bulk assignment which attempts to retain assignment info.

Throws:

java.lang.Exception

testRoundRobinAssignment

public void testRoundRobinAssignment()
                              throws java.lang.Exception
