Hey guys, I have 2 Solr servers set-up, the master is identical to the slave except for the 4 lines of XML that make it a master.
The slave however errors when you try to start it, I have the following set-up to make it a slave:
<requestHandler name="/replication" class="solr.ReplicationHandler" >
<lst name="slave">
<str name="masterUrl">http://10.1.2.196:8080/solr/replication</str>
<str name="pollInterval">00:00:20</str>
</lst>
</requestHandler>
When I comment out the entire request handler for /replication it works fine but with it Solr throws and error and refuses to start.
The error dump is here:

It is also worth noting that both servers are IDENTICAL other than those lines in the config.
Has anyone encountered this before?
The servers themselves use a custom dataDir
<dataDir>/var/lib/solr/data</dataDir> ... 35 more
