Method Detail

setUp

public void setUp()
           throws Exception

Throws:

Exception

testCyclicReplication1

public void testCyclicReplication1()
                            throws Exception

It tests the replication scenario involving 0 -> 1 -> 0. It does it by adding and deleting a row to a table in each cluster, checking if it's replicated. It also tests that the puts and deletes are not replicated back to the originating cluster.

Throws:

Exception

testLoopedReplication

public void testLoopedReplication()
                           throws Exception

Tests the replication scenario 0 -> 0. By default BaseReplicationEndpoint.canReplicateToSameCluster() returns false, so the ReplicationSource should terminate, and no further logs should get enqueued

Throws:

Exception

testHFileCyclicReplication

public void testHFileCyclicReplication()
                                throws Exception

It tests the replication scenario involving 0 -> 1 -> 0. It does it by bulk loading a set of HFiles to a table in each cluster, checking if it's replicated.

Throws:

Exception

testCyclicReplication2

public void testCyclicReplication2()
                            throws Exception

Tests the cyclic replication scenario of 0 -> 1 -> 2 -> 0 by adding and deleting rows to a table in each clusters and ensuring that the each of these clusters get the appropriate mutations. It also tests the grouping scenario where a cluster needs to replicate the edits originating from itself and also the edits that it received using replication from a different cluster. The scenario is explained in HBASE-9158

Throws:

Exception

testHFileMultiSlaveReplication

public void testHFileMultiSlaveReplication()
                                    throws Exception

It tests the multi slave hfile replication scenario involving 0 -> 1, 2. It does it by bulk loading a set of HFiles to a table in master cluster, checking if it's replicated in its peers.

Throws:

Exception

testHFileReplicationForConfiguredTableCfs

public void testHFileReplicationForConfiguredTableCfs()
                                               throws Exception

It tests the bulk loaded hfile replication scenario to only explicitly specified table column families. It does it by bulk loading a set of HFiles belonging to both the CFs of table and set only one CF data to replicate.

Throws:

Exception

testCyclicReplication3

public void testCyclicReplication3()
                            throws Exception

Tests cyclic replication scenario of 0 -> 1 -> 2 -> 1.

Throws:

Exception

tearDown

public void tearDown()
              throws IOException

Throws:

IOException
