Re: Slave replication with custom dataDir

Tue, 02 Nov 2010 07:42:35 -0700

This is a log dump, please be aware that this only appears in my log if I have the following enabled in config. 

<dataDir>/var/lib/solr/data</dataDir>

... snip ...

<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>

Hey guys,

I have 2 instances of Solr running, one as a master, one as a slave.

Both have <dataDir>/var/lib/solr/data</dataDir>

The master works fine, the slave dies with a huge set of stack traces.
The Solr wiki says that replication must match the <dataDir> if it's custom, but how do I actually set that?
