Class IntegrationTestReplication.VerifyReplicationLoop

java.lang.Object

org.apache.hadoop.conf.Configured

org.apache.hadoop.hbase.test.IntegrationTestReplication.VerifyReplicationLoop

All Implemented Interfaces:

org.apache.hadoop.conf.Configurable, org.apache.hadoop.util.Tool

Enclosing class:

IntegrationTestReplication

protected class IntegrationTestReplication.VerifyReplicationLoop
extends org.apache.hadoop.conf.Configured
implements org.apache.hadoop.util.Tool

The main runner loop for the test. It uses IntegrationTestBigLinkedList for the generation and verification of the linked list. It is heavily based on IntegrationTestBigLinkedList.Loop

Method Detail

setupTablesAndReplication

protected void setupTablesAndReplication()
                                  throws Exception

This tears down any tables that existed from before and rebuilds the tables and schemas on the source cluster. It then sets up replication from the source to the sink cluster by using the ReplicationAdmin connection. n

Throws:

Exception

waitForReplication

protected void waitForReplication()
                           throws Exception

Throws:

Exception

runGenerator

protected void runGenerator()
                     throws Exception

Run the IntegrationTestBigLinkedList.Generator in the source cluster. This assumes that the tables have been setup via setupTablesAndReplication. n

Throws:

Exception

runVerify

protected void runVerify(long expectedNumNodes)
                  throws Exception

Run the IntegrationTestBigLinkedList.Verify in the sink cluster. If replication is working properly the data written at the source cluster should be available in the sink cluster after a reasonable gap

Parameters:

expectedNumNodes - the number of nodes we are expecting to see in the sink cluster n

Throws:

Exception

run

public int run(String[] args)
        throws Exception

The main test runner This test has 4 steps: 1: setupTablesAndReplication 2: generate the data into the source cluster 3: wait for replication to propagate 4: verify that the data is available in the sink cluster

Specified by:

run in interface org.apache.hadoop.util.Tool

Parameters:

args - should be empty

Returns:

0 on success

Throws:

Exception - on an error
