类 VerifyReplication

java.lang.Object

org.apache.hadoop.conf.Configured

org.apache.hadoop.hbase.mapreduce.replication.VerifyReplication

所有已实现的接口:

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

public class VerifyReplication
extends org.apache.hadoop.conf.Configured
implements org.apache.hadoop.util.Tool

This map-only job compares the data from a local table with a remote one. Every cell is compared and must have exactly the same keys (even timestamp) as well as same value. It is possible to restrict the job by time range and families. The peer id that's provided must match the one given when the replication stream was setup.

Two counters are provided, Verifier.Counters.GOODROWS and BADROWS. The reason for a why a row is different is shown in the map's log.
