Description

Hi

I am trying to test Solr 1.4 Java replication. It works fine with this configuration on slave and data is sync from master with out any issue

<requestHandler name="/replication" class="solr.ReplicationHandler" >
<lst name="slave">
<str name="masterUrl">http://IP:PORT/SolrSmartPriceSS/replication</str>
<str name="compression">internal</str>
<str name="httpConnTimeout">5000</str>
<str name="httpReadTimeout">10000</str>
</lst>
</requestHandler>

We need to setup repeater on this slave. We have this configuration on slave. With this configuration, it's throwing a null pointer exception. Please see error log

<requestHandler name="/replication" class="solr.ReplicationHandler" >
<lst name="master">
<str name="replicateAfter">commit</str>
<str name="confFiles">schema.xml</str>
</lst>
<lst name="slave">
<str name="masterUrl">http://IP:PORT/SolrSmartPriceSS/replication</str>
<str name="compression">internal</str>
<str name="httpConnTimeout">5000</str>
<str name="httpReadTimeout">10000</str>
</lst>
</requestHandler>
