    {color:red}-1 lineLengths{color}.  The patch introduces the following lines longer than
    +<p>Cluster replication documentation has been moved to the link:http://hbase.apache.org/book.html#_cluster_replication[Cluster
Replication] section of the link:http://hbase.apache.org/book.html[Apache HBase Reference
+. If both clusters use the same ZooKeeper cluster, you must use a different `zookeeper.znode.parent`,
because they cannot write in the same folder.
+. On the source cluster, enable replication by setting `hbase.replication` to `true` in _hbase-site.xml_.
+. On the source cluster, in HBase Shell, add the destination cluster as a peer, using the
`add_peer` command.
+  * CLUSTER_KEY: composed using the following template, with appropriate place-holders: `hbase.zookeeper.quorum:hbase.zookeeper.property.clientPort:zookeeper.znode.parent`
+  Disable a replication relationship. HBase will no longer send edits to that peer cluster,
but it still keeps track of all the new WALs that it will need to replicate if and when it
is re-enabled. 
+  Disable and remove a replication relationship. HBase will no longer send edits to that
peer cluster or keep track of WALs.
+The `VerifyReplication` MapReduce job, which is included in HBase, performs a systematic
comparison of replicated data between two different clusters. Run the VerifyReplication job
on the master cluster, supplying it with the peer ID and table name to use for validation.
You can limit the verification further by specifying a time range or specific families. The
job's short name is `verifyrep`. To run the job, use a command like the following:
+$ HADOOP_CLASSPATH=`${HBASE_HOME}/bin/hbase classpath` "${HADOOP_HOME}/bin/hadoop" jar "${HBASE_HOME}/hbase-server-VERSION.jar"
verifyrep --starttime=<timestamp> --stoptime=<timestamp> --families=<myFam>
<ID> <tableName>
+The `VerifyReplication` command prints out `GOODROWS` and `BADROWS` counters to indicate
rows that did and did not replicate correctly.

    {color:red}-1 site{color}.  The patch appears to cause mvn site goal to fail.

     {color:red}-1 core tests{color}.  The patch failed these unit tests:
