beforeAllTests

public static void beforeAllTests()
                           throws Exception

Throws:

Exception

testImmediateAssignment

public void testImmediateAssignment()
                             throws Exception

Tests immediate assignment. Invariant is that all regions have an assignment.

Throws:

Exception

testBulkAssignment

public void testBulkAssignment()
                        throws 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:

Exception

testRetainAssignment

public void testRetainAssignment()
                          throws Exception

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

Throws:

Exception

testRegionAvailability

public void testRegionAvailability()
                            throws Exception

Throws:

Exception

testRegionAvailabilityWithRegionMoves

public void testRegionAvailabilityWithRegionMoves()
                                           throws Exception

Throws:

Exception

testClusterServersWithSameHostPort
