Yes [1], I set that in hbase-site.xml when I turned on replication. This
box is solely my job-tracker, so maybe it doesn't pick up the
hbase-site.xml? Trying this job from the HMaster didn't work, because it
doesn't have the mapreduce stuff, it seems [2].

[patrick@job-tracker ~]$ grep -A3 replication
/etc/hbase/conf/hbase-site.xml
<name>hbase.replication</name>
<value>true</value>
</property>
</configuration>

[patrick@hmaster ~]$ hadoop jar /usr/lib/hbase/hbase.jar verifyrep
